+# About this issue tracker
+
+*The balena CLI (Command Line Interface) is a tool used to interact with the balena platform.
+This GitHub issue tracker is used for bug reports and feature requests regarding the CLI
+tool. General and troubleshooting questions (such as setting up your project to work with a
+balenalib base image) are encouraged to be posted to the [balena
+forums](https://forums.balena.io), which are monitored by balena's support team and where the
+community can both contribute and benefit from the answers.*
+
+*Please also check that this issue is not a duplicate. If there is another issue describing
+the same problem or feature please add comments to the existing issue.*
+
+*Thank you for your time and effort creating the issue report, and helping us improve the
+balena CLI!*
+
+---
+
+# Expected Behavior
+
+Please describe what you were expecting to happen. If applicable, please add links to
+documentation you were following, or to projects that you were trying to push/build.
+
+# Actual Behavior
+
+Please describe what actually happened instead:
+* Quoting logs and error message is useful. If possible, quote the **full** output of the
+  CLI, not just the error message.
+* Please quote the **full command line** too. Sometimes users report that they were
+  "pushing" or "building" a project, but there are several ways to do so and several
+  possible "targets" such as balenaCloud, openBalena, local balenaOS device, etc.
+  Examples:
+
+```
+balena push myApp
+balena push 192.168.0.12
+balena deploy myApp
+balena deploy myApp --build
+balena build . -a myApp
+balena build . -A armv7hf -d raspberrypi3
+```
+
+Each of the above command lines executes different code behind the scenes, so quoting the
+full command line is very helpful.
+
+Running the CLI in debug mode (`--debug` flag or `DEBUG=1` environment variable) may reveal
+additional information. The `--logs` option reveals additional information for the commands:
+
+```
+balena build . --logs
+balena deploy myApp --build --logs
+```
+
+# Steps to Reproduce the Problem
+
+This is the most important and helpful part of a bug report. If we cannot reproduce the
+problem, it is difficult to tell what the fix should be, or whether code changes have
+fixed it.

+# Contributing
+
+The balena CLI is an open source project and your contribution is welcome!
+
+* Install the dependencies listed in the [NPM Installation](./INSTALL.md#npm-installation)
+  section of the `INSTALL.md` file. Check the section [Additional
+  Dependencies](./INSTALL.md#additional-dependencies) too.
+* Clone the `balena-cli` repository, `cd` to it and run `npm install`.
+* Build the CLI with `npm run build` or `npm test`, and execute it with `./bin/balena`
+  (on a Windows command prompt, you may need to run `node .\bin\balena`).
+
+In order to ease development:
+
+* `npm run build:fast` skips some of the build steps for interactive testing, or
+* `npm run test:source` skips testing the standalone zip packages (which is rather slow)
+* `./bin/balena-dev` uses `ts-node/register` to transpile on the fly.
+
+Before opening a PR, test your changes with `npm test`. Keep compatibility in mind, as the CLI is
+meant to run on Linux, macOS and Windows. balena CI will run test code on all three platforms, but
+this will only help if you add some test cases for your new code!
+
+## ./bin/balena-dev and oclif
+
+When using `./bin/balena-dev` with oclif-converted commands, it is currently necessary to manually
+edit the `oclif` section of `package.json` to replace `./build` with `./lib` as follows:
+
+Change from:
+```
+  "oclif": {
+    "commands": "./build/actions-oclif",
+    "hooks": {
+      "prerun": "./build/hooks/prerun/track"
+```
+
+To:
+```
+  "oclif": {
+    "commands": "./lib/actions-oclif",
+    "hooks": {
+      "prerun": "./lib/hooks/prerun/track"
+```
+
+And then remember to change it back before pushing the pull request. This is obviously error prone
+and inconvenient, and improvement suggestions are welcome: is there a better solution than
+automatically editing `package.json`? It is doable, if it is what needs to be done.
+
+## Semantic versioning and commit messages
+
+The CLI version numbering adheres to [Semantic Versioning](http://semver.org/). The following
+header/row is required in the body of a commit message, and will cause the CI build to fail if absent:
+
+```
+Change-type: patch|minor|major
+```
+
+Version numbers and commit messages are automatically added to the `CHANGELOG.md` file by the CI
+build flow, after a pull request is merged. It should not be manually edited.
+
+## Editing documentation files (CHANGELOG, README, website...)
+
+The `doc/cli.markdown` file is automatically generated by running `npm run build:doc` (which also
+runs as part of `npm run build`). That file is then pulled by scripts in the
+[balena-io/docs](https://github.com/balena-io/docs/) GitHub repo for publishing at the [CLI
+Documentation page](https://www.balena.io/docs/reference/cli/).
+
+The content sources for the auto generation of `doc/cli.markdown` are:
+
+* Selected sections of the README file.
+* The CLI's command documentation in source code (both Capitano and oclif commands), for example:
+  * `lib/actions/build.coffee`
+  * `lib/actions-oclif/env/add.ts`
+
+The README file is manually edited, but subsections are automatically extracted for inclusion in
+`doc/cli.markdown` by the `getCapitanoDoc()` function in
+[`automation/capitanodoc/capitanodoc.ts`](https://github.com/balena-io/balena-cli/blob/master/automation/capitanodoc/capitanodoc.ts).
+
+The `INSTALL.md` and `TROUBLESHOOTING.md` files are also manually edited.
+
+## Windows
+
+Please note that `npm run build:installer` (which generates the `.exe` executable installer on
+Windows) specifically requires [MSYS2](https://www.msys2.org/) to be installed. Other than that,
+the standard Command Prompt or PowerShell can be used (though MSYS2 is still handy, as it provides
+'git' and a number of common unix utilities). If you make changes to `package.json` scripts, check
+they also run on a standard Windows Command Prompt.
+
+## Updating the 'npm-shrinkwrap.json' file
+
+The `npm-shrinkwrap.json` file is used to control package dependencies, as documented at
+https://docs.npmjs.com/files/shrinkwrap.json.
+
+While developing, the `package.json` file is often modified by, or before, running `npm install`
+in order to add, remove or modify dependencies. When `npm install` is executed, it automatically
+updates the `npm-shrinkwrap.json` file as well, **taking into account not only the `package.json`
+file but also the current state of the `node_modules` folder in your computer.**
+
+Meanwhile, as a text (JSON) file, `git` is capable of merging the `npm-shrinkwrap.json` file during
+operations like `rebase`, `cherry-pick` and `pull`. But git's automated merge is not the
+recommended way of updating the `npm-shrinkwrap.json` file, because it does not take into account
+duplicates or conflicts in the dependency tree, or indeed the state of the `package.json` file
+(which may have just been merged). In extreme cases, the automated merge may actually result in a
+broken installation. For these reasons, automatic merging of the `npm-shrinkwrap.json` was disabled
+through the `.gitattributes` file (the "binary merge driver" allows diff'ing but prevents automatic
+merging). Operations like `git rebase` may then result in an error like:
+
+```text
+$ git rebase master
+warning: Cannot merge binary files: npm-shrinkwrap.json (HEAD vs. c34942b9... test)
+Auto-merging npm-shrinkwrap.json
+CONFLICT (content): Merge conflict in npm-shrinkwrap.json
+error: Failed to merge in the changes.
+```
+
+Whether or not there is a merge error, the following commands are the recommended way of updating
+and committing the `npm-shrinkwrap.json` file:
+
+```bash
+$ rm -rf node_modules  # Linux / Mac
+$ rmdir /s node_modules  # Windows Command Prompt
+$ npm checkout master -- npm-shrinkwrap.json  # revert it to the master branch state
+$ npm install  # "cleanly" update the npm-shrinkwrap.json file
+$ git add npm-shrinkwrap.json  # add it for committing (solve merge errors)
+```
+
+## TypeScript and oclif
+
+The CLI currently contains a mix of plain JavaScript and
+[TypeScript](https://www.typescriptlang.org/) code. The goal is to have all code written in
+Typescript, in order to take advantage of static typing and formal programming interfaces.
+The migration towards Typescript is taking place gradually, as part of maintenance work or
+the implementation of new features. Historically, the CLI was originally written in
+[CoffeeScript](https://coffeescript.org), but all CoffeeScript code was migrated to either
+Javascript or Typescript.
+
+Similarly, [Capitano](https://github.com/balena-io/capitano) was originally adopted as the CLI's
+framework, but later we decided to take advantage of [oclif](https://oclif.io/)'s features such
+as native installers for Windows, macOS and Linux, and support for custom flag parsing (for
+example, we're still battling with Capitano's behavior of dropping leading zeros of arguments that
+look like integers, such as some abbreviated UUIDs). Again, the migration is taking place
+gradually, with some CLI commands parsed by oclif and others by Capitano. A simple command line
+pre-parsing takes place in `preparser.ts`, to decide whether to route full parsing to Capitano or
+to oclif.
+
+## Programming style
+
+`npm run build` also runs [balena-lint](https://www.npmjs.com/package/@balena/lint), which automatically
+reformats the code. Beyond that, we have a preference for Javascript promises over callbacks, and for
+`async/await` over `.then()`.
+
+## Updating upstream dependencies
+
+In order to get proper nested changelogs, when updating upstream modules that are in the repo.yml
+(like the balena-sdk), the commit body has to contain a line with the following format:
+```
+Update balena-sdk from 12.0.0 to 12.1.0
+```
+
+Since this is error prone, it's suggested to use the following npm script:
+```
+npm run update balena-sdk ^12.1.0
+```
+
+This will create a new branch (only if you are currently on master), run `npm update` with the
+version you provided as a target and commit the package.json & npm-shrinkwrap.json. The script by
+default will set the `Change-type` to `patch` or `minor`, depending on the semver change of the
+updated dependency, but if you need to use a different one (eg `major`) you can specify it as an
+extra argument:
+```
+npm run update balena-sdk ^12.14.0 patch
+npm run update balena-sdk ^13.0.0 major
+```
+
+## Common gotchas
+
+One thing that most CLI bugs have in common is the absence of test cases exercising the broken
+code, so writing some test code is a great idea. Having said that, there are also some common
+gotchas to bear in mind:
+
+* Forward slashes ('/') _vs._ backslashes ('\') in file paths. The Node.js
+  [path.sep](https://nodejs.org/docs/latest-v12.x/api/path.html#path_path_sep) variable stores a
+  platform-specific path separator character: the backslash on Windows and the forward slash on
+  Linux and macOS. The
+  [path.join](https://nodejs.org/docs/latest-v12.x/api/path.html#path_path_join_paths) function
+  builds paths using such platform-specific path separator. However:
+  * Note that Windows (kernel, cmd.exe, PowerShell, many applications) accepts ***both*** forward
+    slashes and backslashes as path separators (including mixing them in a path string), so code
+    like `mypath.split(path.sep)` may fail on Windows if `mypath` contains forward slashes. The
+    [path.parse](https://nodejs.org/docs/latest-v12.x/api/path.html#path_path_parse_path) function
+    understands both forward slashes and backslashes on Windows, and the
+    [path.normalize](https://nodejs.org/docs/latest-v12.x/api/path.html#path_path_normalize_path)
+    function will _replace_ forward slashes with backslashes.
+  * In [tar](https://en.wikipedia.org/wiki/Tar_(computing)#File_format) streams sent to the Docker
+    daemon and to balenaCloud, the forward slash is the only acceptable path separator, regardless
+    of the OS where the CLI is running. Therefore, `path.sep` and `path.join` should never be used
+    when handling paths in tar streams! `path.posix.join` may be used instead of `path.join`.
+
+* Avoid using the system shell to execute external commands, for example:  
+  `child_process.exec('ssh "arg1" "arg2"');`  
+  `child_process.spawn('ssh "arg1" "arg2"', { shell: true });`  
+  Besides the usual security concerns of unsanitized strings, another problem is to get argument
+  escaping right because of the differences between the Windows 'cmd.exe' shell and the Unix
+  '/bin/sh'. For example, 'cmd.exe' doesn't recognize single quotes like '/bin/sh', and uses the
+  caret (^) instead of the backslash as the escape character. Bug territory! Most of the time,
+  it is possible to avoid relying on the shell altogether by providing a Javascript array of
+  arguments:  
+  `spawn('ssh', ['arg1', 'arg2'], { shell: false});`  
+  To allow for logging and debugging, the [which](https://www.npmjs.com/package/which) package may
+  be used to get the full path of a command before executing it, without relying on any shell:  
+  `const fullPath = await which('ssh');`  
+  `console.log(fullPath);  # 'C:\WINDOWS\System32\OpenSSH\ssh.EXE'`  
+  `spawn(fullPath, ['arg1', 'arg2'], { shell: false });`
+
+* Avoid the `instanceof` operator when testing against classes/types from external packages
+  (including base classes), because `npm install` may result in multiple versions of the same
+  package being installed (to satisfy declared dependencies) and a false negative may result when
+  comparing an object instance from one package version with a class of another package version
+  (even if the implementations are identical in both packages). For example, once we fixed a bug
+  where the test:  
+  `error instanceof BalenaApplicationNotFound`  
+  changed from true to false because `npm install` added an additional copy of the `balena-errors`
+  package to satisfy a minor `balena-sdk` version update:  
+  `$ find node_modules -name balena-errors`  
+  `node_modules/balena-errors`  
+  `node_modules/balena-sdk/node_modules/balena-errors`  
+  In the case of subclasses of `TypedError`, a string comparison may be used instead:  
+  `error.name === 'BalenaApplicationNotFound'`

+# balena CLI Installation Instructions
+
+There are 3 options to choose from to install balena's CLI:
+
+* [Executable Installer](#executable-installer): the easiest method on Windows and macOS, using the
+  traditional graphical desktop application installers.
+* [Standalone Zip Package](#standalone-zip-package): these are plain zip files with the balena CLI
+  executable in them: extract and run. Available for all platforms: Linux, Windows, macOS.
+  Recommended also for scripted installation in CI (continuous integration) environments.
+* [NPM Installation](#npm-installation): recommended for Node.js developers who may be interested
+  in integrating the balena CLI in their existing projects or workflow.
+
+Some specific CLI commands have a few extra installation steps: see section [Additional
+Dependencies](#additional-dependencies).
+
+> **Windows users:**
+> * There is a [YouTube video tutorial](https://www.youtube.com/watch?v=2LApclXFqsg) for installing
+>   and getting started with the balena CLI on Windows. (The video uses the standalone zip package
+>   option.)
+> * If you are using Microsoft's [Windows Subsystem for
+>   Linux](https://docs.microsoft.com/en-us/windows/wsl/about) (WSL), install a balena CLI release
+>   for Linux rather than for Windows, like the standalone zip package for Linux. An installation
+>   with the graphical executable installer for Windows will **not** work with WSL.
+
+## Executable Installer
+
+Recommended for Windows (but not Windows Subsystem for Linux) and macOS:
+
+1. Download the latest installer from the [releases page](https://github.com/balena-io/balena-cli/releases).
+   Look for a file name that ends with "-installer", for example:  
+   `balena-cli-vX.Y.Z-windows-x64-installer.exe`  
+   `balena-cli-vX.Y.Z-macOS-x64-installer.pkg`
+
+2. Double click the downloaded file to run the installer.  
+   _If you are using macOS Catalina (10.15), [check this known issue and
+   workaround](https://github.com/balena-io/balena-cli/issues/1479)._
+
+3. After the installation completes, close and re-open any open [command
+   terminal](https://www.balena.io/docs/reference/cli/#choosing-a-shell-command-promptterminal)
+   windows so that the changes made by the installer to the PATH environment variable can take
+   effect. Check that the installation was successful by running the following commands on a
+   command terminal:
+
+* `balena version` - should print the installed CLI version
+* `balena help` - should print the balena CLI help
+
+> Note: If you had previously installed the CLI using a standalone zip package, it may be a good
+> idea to check your system's `PATH` environment variable for duplicate entries, as the terminal
+> will use the entry that comes first. Check the [Standalone Zip Package](#standalone-zip-package)
+> instructions for how to modify the PATH variable.
+
+By default, the CLI is installed to the following folders:
+
+OS  | Folders
+--- | ---
+Windows: | `C:\Program Files\balena-cli\`
+macOS:   | `/usr/local/lib/balena-cli/` <br> `/usr/local/bin/balena`
+
+## Standalone Zip Package
+
+1. Download the latest zip file from the [releases page](https://github.com/balena-io/balena-cli/releases).
+   Look for a file name that ends with the word "standalone", for example:  
+   `balena-cli-vX.Y.Z-linux-x64-standalone.zip`  ← _also for the Windows Subsystem for Linux_  
+   `balena-cli-vX.Y.Z-macOS-x64-standalone.zip`  
+   `balena-cli-vX.Y.Z-windows-x64-standalone.zip`
+
+2. Extract the zip file contents to any folder you choose. The extracted contents will include a
+   `balena-cli` folder.
+
+3. Add the `balena-cli` folder to the system's `PATH` environment variable.  
+   See instructions for:
+   [Linux](https://stackoverflow.com/questions/14637979/how-to-permanently-set-path-on-linux-unix) |
+   [macOS](https://www.architectryan.com/2012/10/02/add-to-the-path-on-mac-os-x-mountain-lion/#.Uydjga1dXDg) |
+   [Windows](https://www.computerhope.com/issues/ch000549.htm)
+
+> * If you are using macOS Catalina (10.15), [check this known issue and
+>   workaround](https://github.com/balena-io/balena-cli/issues/1479).
+> * **Linux Alpine** and **Busybox:** the standalone zip package is not currently compatible with
+>   these "compact" Linux distributions, because of the alternative C libraries they ship with.
+>   It should however work with all "desktop" or "server" distributions, e.g. Ubuntu, Debian, Suse,
+>   Fedora, Arch Linux and many more.
+> * Note that moving the `balena` executable out of the extracted `balena-cli` folder on its own
+>   (e.g. moving it to `/usr/local/bin/balena`) will **not** work, as it depends on the other
+>   folders and files also present in the `balena-cli` folder.
+
+To update the CLI to a new version, download a new release zip file and replace the previous
+installation folder. To uninstall, simply delete the folder and edit the PATH environment variable
+as described above.
+
+## NPM Installation
+
+If you are a Node.js developer, you may wish to install the balena CLI via [npm](https://www.npmjs.com).
+The npm installation involves building native (platform-specific) binary modules, which require
+some additional development tools to be installed first:
+
+* [Node.js](https://nodejs.org/) version 10 (min **10.20.0**) or 12 (version 14 is not yet fully supported)
+  * **Linux, macOS** and **Windows Subsystem for Linux (WSL):**  
+    Installing Node via [nvm](https://github.com/nvm-sh/nvm/blob/master/README.md) is recommended.
+    When the "system" or "default" Node.js and npm packages are installed with "apt-get" in Linux
+    distributions like Ubuntu, users often report permission or compilation errors when running
+    "npm install". This [sample
+    Dockerfile](https://gist.github.com/pdcastro/5d4d96652181e7da685a32caf629dd44) shows the CLI
+    installation steps on an Ubuntu 18.04 base image.
+* [Python 2.7](https://www.python.org/), [git](https://git-scm.com/), [make](https://www.gnu.org/software/make/), [g++](https://gcc.gnu.org/)
+  * **Linux** and **Windows Subsystem for Linux (WSL):**  
+    `sudo apt-get install -y python git make g++`
+  * **macOS:** install Apple's Command Line Tools by running on a Terminal window:  
+    `xcode-select --install`
+
+On **Windows (not WSL),** the dependencies above and additional ones can be met by installing:
+
+* Node.js from the [Nodejs.org download page](https://nodejs.org/en/download/).
+* The [MSYS2 shell](https://www.msys2.org/), which provides `git`, `make`, `g++`, `ssh`, `rsync`
+  and more:
+  * `pacman -S git openssh rsync gcc make`
+  * [Set a Windows environment variable](https://www.onmsft.com/how-to/how-to-set-an-environment-variable-in-windows-10): `MSYS2_PATH_TYPE=inherit`
+  * Note that a bug in the MSYS2 launch script (`msys2_shell.cmd`) makes text-based
+    interactive CLI menus to misbehave. [Check this Github issue for a
+    workaround](https://github.com/msys2/MINGW-packages/issues/1633#issuecomment-240583890).
+* The Windows Driver Kit (WDK), which is needed to compile some native Node modules. It is **not**
+  necessary to install Visual Studio, only the WDK, which is "step 2" in the following guides:
+  * [WDK for Windows 10](https://docs.microsoft.com/en-us/windows-hardware/drivers/download-the-wdk#download-icon-step-2-install-wdk-for-windows-10-version-1903)
+  * [WDK for earlier versions of Windows](https://docs.microsoft.com/en-us/windows-hardware/drivers/other-wdk-downloads#step-2-install-the-wdk)
+* The [windows-build-tools](https://www.npmjs.com/package/windows-build-tools) npm package (which
+  provides Python 2.7 and more), by running the following command on an [administrator
+  console](https://www.howtogeek.com/194041/how-to-open-the-command-prompt-as-administrator-in-windows-8.1/):
+  
+  `npm install -g --production windows-build-tools`
+
+With these dependencies in place, the balena CLI installation command is:
+
+```sh
+$ npm install balena-cli -g --production --unsafe-perm
+```
+
+`--unsafe-perm` is required when `npm install` is executed as the root user, or on systems where
+the global install directory is not user-writable. It allows npm install steps to download and save
+prebuilt native binaries, and also allows the execution of npm scripts like `postinstall` that are
+used to patch dependencies. It is usually possible to omit `--unsafe-perm` if installing under a
+regular (non-root) user account, especially if using a user-managed node installation such as
+[nvm](https://github.com/creationix/nvm).
+
+
+## Additional Dependencies
+
+* The `balena ssh` command requires a recent version of the `ssh` command-line tool to be available:
+  * macOS and Linux usually already have it installed. Otherwise, search for the available packages
+    on your specific Linux distribution, or for the Mac consider the [Xcode command-line
+    tools](https://developer.apple.com/xcode/features/) or [homebrew](https://brew.sh/).
+
+  * Microsoft started distributing an SSH client with Windows 10, which we understand is
+    automatically installed through Windows Update, but can be manually installed too
+    ([more information](https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse)).
+    For other versions of Windows, there are several ssh/OpenSSH clients provided by 3rd parties.
+
+  * The [`proxytunnel`](http://proxytunnel.sourceforge.net/) package (command-line tool) is needed
+    for the `balena ssh` command to work behind a proxy. It is available for Linux distributions
+    like Ubuntu/Debian (`apt install proxytunnel`), and for macOS through
+    [Homebrew](https://brew.sh/). Windows support is limited to the Windows Subsystem for Linux
+    (e.g., by installing Ubuntu through the Microsoft App Store). Check the
+    [README](https://github.com/balena-io/balena-cli/blob/master/README.md) file for proxy
+    configuration instructions.
+
+* The `balena preload`, `balena build` and `balena deploy --build` commands require
+  [Docker](https://docs.docker.com/install/overview/) or [balenaEngine](https://www.balena.io/engine/)
+  to be available:
+  * The `balena preload` command requires the Docker Engine to support the [AUFS storage
+    driver](https://docs.docker.com/storage/storagedriver/aufs-driver/). Docker Desktop for Mac and
+    Windows dropped support for the AUFS filesystem in Docker CE versions greater than 18.06.1, so
+    the workaround is to downgrade to version 18.06.1 (links: [Docker CE for
+    Windows](https://docs.docker.com/docker-for-windows/release-notes/#docker-community-edition-18061-ce-win73-2018-08-29)
+    and [Docker CE for
+    Mac](https://docs.docker.com/docker-for-mac/release-notes/#docker-community-edition-18061-ce-mac73-2018-08-29)).
+    See more details in [CLI issue 1099](https://github.com/balena-io/balena-cli/issues/1099).
+  * Commonly, Docker is installed on the same machine where the CLI is being used, but the
+    `balena build` and `balena deploy` commands can also use a remote Docker Engine (daemon)
+    or balenaEngine (which could be a remote device running a [balenaOS development
+    image](https://www.balena.io/docs/reference/OS/overview/2.x/#dev-vs-prod-images)) by specifying
+    its IP address and port number as command-line options. Check the documentation for each
+    command, e.g. `balena help build`, or the [online
+    reference](https://www.balena.io/docs/reference/cli/#cli-command-reference).
+  * If you are using Microsoft's [Windows Subsystem for
+    Linux](https://docs.microsoft.com/en-us/windows/wsl/about) (WSL) and Docker Desktop for
+    Windows, check the [FAQ item "Docker seems to be
+    unavailable"](https://github.com/balena-io/balena-cli/blob/master/TROUBLESHOOTING.md#docker-seems-to-be-unavailable-error-when-using-windows-subsystem-for-linux-wsl).
+
+* The `balena scan` command requires a multicast DNS (mDNS) service like Bonjour or Avahi:
+  * On Windows, check if 'Bonjour' is installed (Control Panel > Programs and Features).
+    If not, you can download Bonjour for Windows from https://support.apple.com/kb/DL999
+  * Most 'desktop' Linux distributions ship with [Avahi](https://en.wikipedia.org/wiki/Avahi_(software)).
+    Search for the installation command for your distribution. E.g. for Ubuntu:
+    `sudo apt-get install avahi-daemon`
+  * macOS comes with [Bonjour](https://en.wikipedia.org/wiki/Bonjour_(software)) built-in.
+  
+* The `balena os configure` command is currently not supported on Windows natively. Windows users are advised 
+  to install the [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/about) (WSL) 
+  with Ubuntu, and use the Linux release of the balena CLI.
+  
+
+## Configuring SSH keys
+
+The `balena ssh` command requires an SSH key to be added to your balena account. If you had
+already added a SSH key in order to [deploy with 'git push'](https://www.balena.io/docs/learn/getting-started/raspberrypi3/nodejs/#adding-an-ssh-key),
+then you are probably done and may skip this section. You can check whether you already have
+an SSH key in your balena account with the `balena keys` command, or by visiting the
+[balena web dashboard](https://dashboard.balena-cloud.com/), clicking on your name -> Preferences
+-> SSH Keys.
+
+> Note: An "SSH key" actually consists of a public/private key pair. A typical name for the private
+> key file is "id_rsa", and a typical name for the public key file is "id_rsa.pub". Both key files
+> are saved to your computer (with the private key optionally protected by a password), but only
+> the public key is saved to your balena account. This means that if you change computers or
+> otherwise lose the private key, _you cannot recover the private key through your balena account._
+> You can however add new keys, and delete the old ones.
+
+If you don't have an SSH key in your balena account:
+
+* If you have an existing SSH key in your computer that you would like to use, you can add it
+  to your balena account through the balena web dashboard (Preferences -> SSH Keys), or through
+  the CLI itself:
+
+```bash
+# Windows 10 (cmd.exe prompt) example:
+$ balena key add MyKey %userprofile%\.ssh\id_rsa.pub
+# Linux / macOS example:
+$ balena key add MyKey ~/.ssh/id_rsa.pub
+```
+
+* To generate a new key, you can follow [GitHub's documentation](https://help.github.com/en/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent),
+  skipping the step about adding the key to your GitHub account, and instead adding the key to
+  your balena account as described above.

-----------
+## About
 
-- [NodeJS](https://nodejs.org) (>= v4)
-- [Git](https://git-scm.com)
-- The following executables should be correctly installed in your shell environment:
-  - `ssh`: Any recent version of the OpenSSH ssh client (required by `resin sync` and `resin ssh`)
-	- if you need `ssh` to work behind the proxy you also need [`proxytunnel`](http://proxytunnel.sourceforge.net/) installed (available as `proxytunnel` package for Ubuntu, for example)
-  - `rsync`: >= 2.6.9 (required by `resin sync`)
+The balena CLI (Command-Line Interface) allows you to interact with the balenaCloud and the
+[balena API](https://www.balena.io/docs/reference/api/overview/) through a terminal window
+on Linux, macOS or Windows. You can also write shell scripts around it, or import its Node.js
+modules to use it programmatically.
+As an [open-source project on GitHub](https://github.com/balena-io/balena-cli/), your contribution
+is also welcome!
 
-##### Windows Support
+## Installation
 
-Before installing resin-cli, you'll need a working node-gyp environment. If you don't already have one you'll see native module build errors during installation. To fix this, run `npm install -g --production windows-build-tools` in an administrator console (available as 'Command Prompt (Admin)' when pressing windows+x in Windows 7+).
+Check the [balena CLI installation instructions on GitHub](https://github.com/balena-io/balena-cli/blob/master/INSTALL.md).
 
-`resin sync` and `resin ssh` have not been thoroughly tested on the standard Windows cmd.exe shell. We recommend using bash (or a similar) shell, like Bash for Windows 10 or [Git for Windows](https://git-for-windows.github.io/).
+## Getting Started
 
-If you still want to use `cmd.exe` you will have to use a package manager like MinGW or chocolatey. For MinGW the steps are:
+### Choosing a shell (command prompt/terminal)
 
-1. Install [MinGW](http://www.mingw.org).
-2. Install the `msys-rsync` and `msys-openssh` packages.
-3. Add MinGW to the `%PATH%` if this hasn't been done by the installer already. The location where the binaries are places is usually `C:\MinGW\msys\1.0\bin`, but it can vary if you selected a different location in the installer.
-4. Copy your SSH keys to `%homedrive%%homepath\.ssh`.
-5. If you need `ssh` to work behind the proxy you also need to install [proxytunnel](http://proxytunnel.sourceforge.net/)
+On **Windows,** the standard Command Prompt (`cmd.exe`) and
+[PowerShell](https://docs.microsoft.com/en-us/powershell/scripting/getting-started/getting-started-with-windows-powershell?view=powershell-6)
+are supported. We are aware of users also having a good experience with alternative shells,
+including:
 
-Getting Started
----------------
+* [MSYS2](https://www.msys2.org/):
+  * Install additional packages with the command:  
+    `pacman -S git openssh rsync`
+  * [Set a Windows environment variable](https://www.onmsft.com/how-to/how-to-set-an-environment-variable-in-windows-10): `MSYS2_PATH_TYPE=inherit`
+  * Note that a bug in the MSYS2 launch script (`msys2_shell.cmd`) makes text-based interactive CLI
+    menus to break. [Check this Github issue for a
+    workaround](https://github.com/msys2/MINGW-packages/issues/1633#issuecomment-240583890).
+* [MSYS](http://www.mingw.org/wiki/MSYS): select the `msys-rsync` and `msys-openssh` packages too
+* [Git for Windows](https://git-for-windows.github.io/)
+  * During the installation, you will be prompted to choose between _"Use MinTTY"_ and _"Use
+    Windows' default console window"._ Choose the latter, because of the same [MSYS2
+    bug](https://github.com/msys2/MINGW-packages/issues/1633) mentioned above (Git for Windows
+    actually uses MSYS2). For a screenshot, check this
+    [comment](https://github.com/balena-io/balena-cli/issues/598#issuecomment-556513098).
+* Microsoft's [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/about)
+  (WSL). In this case, a Linux distribution like Ubuntu is installed via the Microsoft Store, and a
+  balena CLI release **for Linux** is recommended. See
+  [FAQ](https://github.com/balena-io/balena-cli/blob/master/TROUBLESHOOTING.md) for using balena
+  CLI with WSL and Docker Desktop for Windows.
 
-### Install
+On **macOS** and **Linux,** the standard terminal window is supported. _Optionally,_ `bash` command
+auto completion may be enabled by copying the
+[balena-completion.bash](https://github.com/balena-io/balena-cli/blob/master/balena-completion.bash)
+file to your system's `bash_completion` directory: check [Docker's command completion
+guide](https://docs.docker.com/compose/completion/) for system setup instructions.
 
-This might require elevated privileges in some environments.
+### Logging in
+
+Several CLI commands require access to your balenaCloud account, for example in order to push a
+new release to your application. Those commands require creating a CLI login session by running:
 
 ```sh
-$ npm install --global --production resin-cli
+$ balena login
 ```
 
-### Login
+### Proxy support
 
-```sh
-$ resin login
+HTTP(S) proxies can be configured through any of the following methods, in precedence order
+(from higher to lower):
+
+* The `BALENARC_PROXY` environment variable in URL format, with protocol (`http` or `https`),
+  host, port and optionally basic auth. Examples:
+  * `export BALENARC_PROXY='https://bob:secret@proxy.company.com:12345'`
+  * `export BALENARC_PROXY='http://localhost:8000'`
+
+* The `proxy` setting in the [CLI config
+  file](https://www.npmjs.com/package/balena-settings-client#documentation). It may be:
+  * A string in URL format, e.g. `proxy: 'http://localhost:8000'`
+  * An object in the format:
+
+    ```yaml
+    proxy:
+        protocol: 'http'
+        host: 'proxy.company.com'
+        port: 12345
+        proxyAuth: 'bob:secret'
+    ```
+
+* The `HTTPS_PROXY` and/or `HTTP_PROXY` environment variables, in the same URL format as
+  `BALENARC_PROXY`.
+
+> Note: The `balena ssh` command has additional setup requirements to work behind a proxy.
+> Check the [installation instructions](https://github.com/balena-io/balena-cli/blob/master/INSTALL.md),
+> and ensure that the proxy server is configured to allow proxy requests to ssh port 22, using
+> SSL encryption. For example, in the case of the [Squid](http://www.squid-cache.org/) proxy
+> server, it should be configured with the following rules in the `squid.conf` file:  
+> `acl SSL_ports port 22`  
+> `acl Safe_ports port 22`  
+
+#### Proxy exclusion
+
+The `BALENARC_NO_PROXY` variable may be used to exclude specified destinations from proxying.
+
+> * This feature requires balena CLI version 11.30.8 or later. In the case of the npm [installation
+>   option](https://github.com/balena-io/balena-cli/blob/master/INSTALL.md), it also requires
+>   Node.js version 10.16.0 or later.
+> * To exclude a `balena ssh` target from proxying (IP address or `.local` hostname), the
+>   `--noproxy` option should be specified in addition to the `BALENARC_NO_PROXY` variable.
+
+By default (if `BALENARC_NO_PROXY` is not defined), all [private IPv4
+addresses](https://en.wikipedia.org/wiki/Private_network) and `'*.local'` hostnames are excluded
+from proxying. Other hostnames that resolve to private IPv4 addresses are **not** excluded by
+default, because matching takes place before name resolution.
+
+`localhost` and `127.0.0.1` are always excluded from proxying, regardless of the value of
+BALENARC_NO_PROXY.
+
+The format of the `BALENARC_NO_PROXY` environment variable is a comma-separated list of patterns
+that are matched against hostnames or IP addresses. For example:
+
+```
+export BALENARC_NO_PROXY='*.local,dev*.mycompany.com,192.168.*'
 ```
 
-_(Typically useful, but not strictly required for all commands)_
+Matched patterns are excluded from proxying. Wildcard expressions are documented at
+[matcher](https://www.npmjs.com/package/matcher#usage). Matching takes place _before_ name
+resolution, so a pattern like `'192.168.*'` will **not** match a hostname that resolves to an IP
+address like `192.168.1.2`.
 
-### Run commands
+## Command reference documentation
 
-Take a look at the full command documentation at [https://docs.resin.io/tools/cli/](https://docs.resin.io/tools/cli/#table-of-contents

-FAQ
----
+## Deprecation policy
 
-### Where is my configuration file?
+The balena CLI uses [semver versioning](https://semver.org/), with the concepts
+of major, minor and patch version releases.
 
-The per-user configuration file lives in `$HOME/.resinrc.yml` or `%UserProfile%\_resinrc.yml`, in Unix based operating systems and Windows respectively.
+The latest release of the previous major version of the balena CLI will remain
+compatible with the balenaCloud backend services for one year from the date when
+the next major version is released. For example, balena CLI v10.17.5, as the
+latest v10 release, would remain compatible with the balenaCloud backend for one
+year from the date when v11.0.0 is released.
 
-The Resin CLI also attempts to read a `resinrc.yml` file in the current directory, which takes precedence over the per-user configuration file.
+At the end of this period, the older major version is considered deprecated and
+some of the functionality that depends on balenaCloud services may stop working
+at any time.
+Users are encouraged to regularly update the balena CLI to the latest version.
 
-### How do I point the Resin CLI to staging?
+## Contributing (including editing documentation files)
 
-The easiest way is to set the `RESINRC_RESIN_URL=resinstaging.io` environment variable.
+Please have a look at the [CONTRIBUTING.md](./CONTRIBUTING.md) file for some guidance before
+submitting a pull request or updating documentation (because some files are automatically
+generated). Thank you for your help and interest!
 
-Alternatively, you can edit your configuration file and set `resinUrl: resinstaging.io` to persist this setting.
+## License
 
-### How do I make the Resin CLI persist data in another directory?
-
-The Resin CLI persists your session token, as well as cached images in `$HOME/.resin` or `%UserProfile%\_resin`.
-
-Pointing the Resin CLI to persist data in another location is necessary in certain environments, like a server, where there is no home directory, or a device running resinOS, which erases all data after a restart.
-
-You can accomplish this by setting `RESINRC_DATA_DIRECTORY=/opt/resin` or adding `dataDirectory: /opt/resin` to your configuration file, replacing `/opt/resin` with your desired directory.

 - Some interactive widgets don't work on `Cygwin`. If you're running Windows, it's preferrable that you use `cmd.exe`, as `Cygwin` is [not official supported by Node.js](https://github.com/chjj/blessed/issues/56#issuecomment-42671945).
 
-### I get `Invalid MBR boot signature` when configuring a device
+## I get `Invalid MBR boot signature` when configuring a device
 
 This error, accompanied with something like: `Expected 0xAA55, but saw 0x29FE` usually indicates a corrupted device operating system image in the cache, due to bad a internet connection during the download process.
 
 Try clearing the cache with the following command and trying again:
 
 ```sh
-$ rm -rf $HOME/.resin/cache
+$ rm -rf $HOME/.balena/cache
 ```
 
 Or in Windows:
 
 ```sh
-> del /s /q %UserProfile%\_resin\cache
+> del /s /q %UserProfile%\_balena\cache
 ```
 
-### I get `EACCES: permission denied` when logging in
+## I get `EACCES: permission denied` when logging in
 
-The Resin CLI stores the session token in `$HOME/.resin` or `C:\Users\<user>\_resin` in UNIX based operating systems and Windows respectively. This error usually indicates that the user doesn't have permissions over that directory, which can happen if you ran the Resin CLI as `root`, and thus the directory got owned by him.
+The balena CLI stores the session token in `$HOME/.balena` or `C:\Users\<user>\_balena` in UNIX based operating systems and Windows respectively. This error usually indicates that the user doesn't have permissions over that directory, which can happen if you ran the balena CLI as `root`, and thus the directory got owned by him.
 
 Try resetting the ownership by running:
 
 ```sh
-$ sudo chown -R <user> $HOME/.resin
+$ sudo chown -R <user> $HOME/.balena
 ```
+
+## Broken line wrapping / cursor behavior with `balena ssh`
+
+Users sometimes come across broken line wrapping or cursor behavior in text terminals, for example when long command lines are typed in a `balena ssh` session, or when using text editors like `vim` or `nano`. This is not something specific to the balena CLI, being also a commonly reported issue with standard remote terminal tools like `ssh` or `telnet`. It is often a remote shell configuration issue (files like `/etc/profile`, `~/.bash_profile`, `~/.bash_login`, `~/.profile` and the like), including UTF-8 misconfiguration, the use of unsupported ASCII control characters in shell prompt formatting (e.g. the `$PS1` env var) or the output of tools or log files that use colored text. The issue can sometimes be fixed by resizing the client terminal window, or by running one or more of the following commands on the shell:
+
+```sh
+export TERMINAL=linux
+stty sane
+shopt -s checkwinsize
+bind 'set horizontal-scroll-mode off'
+```
+
+Terminal multiplexer tools like GNU `screen` or `tmux` are sometimes reported to fix the issues, though at other times they are reported as the _cause_ of the problem. They have their own configuration files to take into account.
+

+* https://unix.stackexchange.com/questions/529377/terminal-long-line-wrapping
+* https://github.com/microsoft/WSL/issues/1436
+
+If nothing seems to help, consider also using a different client-side terminal application:
+* Linux: xterm, KDE Konsole, GNOME Terminal
+* Mac: Terminal, iTerm2
+* Windows: PowerShell, PuTTY, WSL (Windows Subsystem for Linux)
+
+## "Docker seems to be unavailable" error when using Windows Subsystem for Linux (WSL)
+
+When running on WSL, the recommendation is to install a CLI release for Linux, like the standalone
+zip package for Linux. However, commands like "balena build" that contact a local Docker daemon,
+like the Docker Desktop for Windows, will try to reach Docker at the Unix socket path
+`/var/run/docker.sock`, while Docker Desktop for Windows uses a Windows named pipe at
+`//./pipe/docker_engine` (which the Linux CLI on WSL cannot use). A solution is:
+
+- Open the Docker Desktop for Windows settings panel and tick the checkbox _"Expose daemon on tcp://localhost:2375 without TLS"._
+- On the WSL command line, set an env var:  
+`export DOCKER_HOST=tcp://localhost:2375`  
+Alternatively, use the command-line options `-h 127.0.0.1 -p 2375` for commands like `balena build` and `balena deploy`.

-	title: 'Resin CLI Documentation'
-	introduction: '''
-		This tool allows you to interact with the resin.io api from the comfort of your command line.
-
-		Please make sure your system meets the requirements as specified in the [README](https://github.com/resin-io/resin-cli).
-
-		To get started download the CLI from npm.
-
-			$ npm install resin-cli -g
-
-		Then authenticate yourself:
-
-			$ resin login
-
-		Now you have access to all the commands referenced below.
-
-		## Proxy support
-
-		The CLI does support HTTP(S) proxies.
-
-		You can configure the proxy using several methods (in order of their precedence):
-
-		* set the `RESINRC_PROXY` environment variable in the URL format (with protocol, host, port, and optionally the basic auth),
-		* use the [resin config file](https://www.npmjs.com/package/resin-settings-client#documentation) (project-specific or user-level)
-		and set the `proxy` setting. This can be:
-			* a string in the URL format,
-			* or an object following [this format](https://www.npmjs.com/package/global-tunnel-ng#options), which allows more control,
-		* or set the conventional `https_proxy` / `HTTPS_PROXY` / `http_proxy` / `HTTP_PROXY`
-		environment variable (in the same standard URL format).
