+**IMPORTANT**
+
+The file [`capitanodoc.ts`](https://github.com/balena-io/balena-cli/blob/master/automation/capitanodoc/capitanodoc.ts) lists 
+commands to generate documentation from. At the moment, it's manually updated and maintained alphabetically. 
+
+To add a new command to be documented, 
+
+1. Find the resource which it is part of or create a new one. 
+2. List the location of the build file 
+3. Make sure to add your files in alphabetical order
+4. Resources with plural names needs to have 2 sections if they have commands like: "fleet, fleets" or "device, devices" or "tag, tags"
+
+Once added, run the command `npm run build` to generate the documentation
+
 The `INSTALL*.md` and `TROUBLESHOOTING.md` files are also manually edited.
 
+## Patches folder
+
+The `patches` folder contains patch files created with the
+[patch-package](https://www.npmjs.com/package/patch-package) tool. Small code changes to
+third-party modules can be made by directly editing Javascript files under the `node_modules`
+folder and then running `patch-package` to create the patch files. The patch files are then
+applied immediately after `npm install`, through the `postinstall` script defined in
+`package.json`.
+
+The subfolders of the `patches` folder are documented in the
+[apply-patches.js](https://github.com/balena-io/balena-cli/blob/master/patches/apply-patches.js)
+script.
+
+To make changes to the patch files under the `patches` folder, **do not edit them directly,**
+not even for a "single character change" because the hash values in the patch files also need
+to be recomputed by `patch-packages`. Instead, edit the relevant files under `node_modules`
+directly, and then run `patch-packages` with the `--patch-dir` option to specify the subfolder
+where the patch should be saved. For example, edit `node_modules/exit-hook/index.js` and then
+run:
+
+```sh
+$ npx patch-package --patch-dir patches/all exit-hook
+```
+
+That said, these kinds of patches should be avoided in favour of creating pull requests
+upstream. Patch files create additional maintenance work over time as the patches need to be
+updated when the dependencies are updated, and they prevent the compounding community benefit
+that sharing fixes upstream have on open source projects like the balena CLI. The typical
+scenario where these patches are used is when the upstream maintainers are unresponsive or
+unwilling to merge the required fixes, the fixes are very small and specific to the balena CLI,
+and creating a fork of the upstream repo is likely to be more long-term effort than maintaining
+the patches.
+
 ## Windows
 
-The `npm run build:installer` script (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 changes are made to npm scripts in `package.json`,
-check that they also run on a standard Windows Command Prompt.
+Besides the regular npm installation dependencies, the `npm run build:installer` script
+that produces the `.exe` graphical installer on Windows also requires
+[NSIS](https://sourceforge.net/projects/nsis/) and [MSYS2](https://www.msys2.org/) to be
+installed. Be sure to add `C:\Program Files (x86)\NSIS` to the PATH, so that `makensis`
+is available. MSYS2 is recommended when developing the balena CLI on Windows.
+
+If changes are made to npm scripts in `package.json`, don't assume that a Unix shell like
+bash is available. For example, some Windows shells don't have the `cp` and `rm` commands,
+which is why you'll often find `ncp` and `rimraf` used in `package.json` scripts.

+## `fast-boot` and `npm link` - modifying the `node_modules` folder
+
+During development or debugging, it is sometimes useful to temporarily modify the `node_modules`
+folder (with or without making the respective changes to the `npm-shrinkwrap.json` file),
+replacing dependencies with different versions. This can be achieved with the `npm link`
+command, or by manually editing or copying files to the `node_modules` folder.
+
+Unexpected behavior may then be observed because of the CLI's use of the
+[fast-boot2](https://www.npmjs.com/package/fast-boot2) package that caches module resolution.
+`fast-boot2` is configured in `lib/fast-boot.ts` to automatically invalidate the cache if
+changes are made to the `package.json` or `npm-shrinkwrap.json` files, but the cache won't
+be automatically invalidated if `npm link` is used or if manual modifications are made to the
+`node_modules` folder. In this situation:
+
+* Manually delete the module cache file (typically `~/.balena/cli-module-cache.json`), or
+* Use the `bin/balena-dev` entry point (instead of `bin/balena`) as it does not activate
+  `fast-boot2`.

+following major version is released. For example, balena CLI v11.36.0, as the
+latest v11 release, would remain compatible with the balenaCloud backend for one
+year from the date when v12.0.0 was released.
 
-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.
+Half way through to that period (6 months after the release of the next major
+version), older major versions of the balena CLI will start printing a deprecation
+warning message when it is used interactively (when `stderr` is attached to a TTY
+device file). At the end of that period, older major versions will exit with an
+error message unless the `--unsupported` flag is used.  This behavior was
+introduced in CLI version 12.47.0 and is also documented by `balena help`.
+To take advantage of the latest backend features and ensure compatibility, users
+are encouraged to regularly update the balena CLI to the latest version.

-# Provisioning balena devices in automated (non-interactive) mode
-
-This document describes how to run the `device init` command in non-interactive mode.
-
-It requires collecting some preliminary information _once_.
-
-The final command to provision the device looks like this:
-
-```bash
-balena device init --app APP_ID --os-version OS_VERSION --drive DRIVE --config CONFIG_FILE --yes
-
-```
-
-You can run this command as many times as you need, putting the new medium (SD card / USB stick) each time.
-
-But before you can run it you need to collect the parameters and build the configuration file. Keep reading to figure out how to do it.
-
-
-## Collect all the required parameters.
-
-1. `DEVICE_TYPE`. Run
-	```bash
-	balena devices supported
-	```
-	and find the _slug_ for your target device type, like _raspberrypi3_.
-
-1. `APP_ID`. Create an application (`balena app create APP_NAME --type DEVICE_TYPE`) or find an existing one (`balena apps`) and notice its ID.
-
-1. `OS_VERSION`. Run
-	```bash
-	balena os versions DEVICE_TYPE
-	```
-	and pick the version that you need, like _v2.0.6+rev1.prod_.
-	_Note_ that even though we support _semver ranges_ it's recommended to use the exact version when doing the automated provisioning as it
-	guarantees full compatibility between the steps.
-
-1. `DRIVE`. Plug in your target medium (SD card or the USB stick, depending on your device type) and run
-	```bash
-	balena util available-drives
-	```
-	and get the drive name, like _/dev/sdb_ or _/dev/mmcblk0_.
-	The balena CLI will not display the system drives to protect you,
-	but still please check very carefully that you've picked the correct drive as it will be erased during the provisioning process.
-
-Now we have all the parameters -- time to build the config file.
-
-## Build the config file
-
-Interactive device provisioning process often includes collecting some extra device configuration, like the networking mode and wifi credentials.
-
-To skip this interactive step we need to buid this configuration once and save it to the JSON file for later reuse.
-
-Let's say we will place it into the `CONFIG_FILE` path, like _./balena-os/raspberrypi3-config.json_.
-
-We also need to put the OS image somewhere, let's call this path `OS_IMAGE_PATH`, it can be something like _./balena-os/raspberrypi3-v2.0.6+rev1.prod.img_.
-
-1. First we need to download the OS image once. That's needed for building the config, and will speedup the subsequent operations as the downloaded OS image is placed into the local cache.
-
-	Run:
-	```bash
-	balena os download DEVICE_TYPE --output OS_IMAGE_PATH --version OS_VERSION
-	```
-
-1. Now we're ready to build the config:
-
-	```bash
-	balena os build-config OS_IMAGE_PATH DEVICE_TYPE --output CONFIG_FILE
-	```
-
-	This will run you through the interactive configuration wizard and in the end save the generated config as `CONFIG_FILE`. You can then verify it's not empty:
-
-	```bash
-	cat CONFIG_FILE
-	```
-
-## Done
-
-Now you're ready to run the command in the beginning of this guide.
-
-Please note again that all of these steps only need to be done once (unless you need to change something), and once all the parameters are collected the main init command can be run unchanged.
-
-But there are still some nuances to cover, please read below. 
-
-## Nuances
-
-### `sudo` password on *nix systems
-
-In order to write the image to the raw device we need the root permissions, this is unavoidable.
-
-To improve the security we only run the minimal subcommand with `sudo`.
-
-This means that with the default setup you're interrupted closer to the end of the device init process to enter your sudo password for this subcommand to work.
-
-There are several ways to eliminate it and make the process fully non-interactive.
-
-#### Option 1: make passwordless sudo.
-
-Obviously you shouldn't do that if the machine you're working on has access to any sensitive resources or information.
-
-But if you're using a machine dedicated to balena provisioning this can be fine, and also the simplest thing to do.
-
-#### Option 2: `NOPASSWD` directive
-
-You can configure the `balena` CLI command to be sudo-runnable without the password. Check [this post](https://askubuntu.com/questions/159007/how-do-i-run-specific-sudo-commands-without-a-password) for an example.
-
-### Extra initialization config
-
-As of June 2017 all the supported devices should not require any other interactive configuration.
-
-But by the design of our system it is _possible_ (though it doesn't look very likely it's going to happen any time soon) that some extra initialization options may be requested for the specific device types.
-
-If that is the case please raise the issue in the balena CLI repository and the maintainers will add the necessary options to build the similar JSON config for this step.
