 # Sync
 
-## sync [source]
+## sync [uuid]
 
 WARNING: If you're running Windows, this command only supports `cmd.exe`.
 
 Use this command to sync your local changes to a certain device on the fly.
 
-The `source` argument can be either a device uuid or an application name.
+After every 'resin sync' the updated settings will be saved in
+'<source>/.resin-sync.yml' and will be used in later invocations. You can
+also change any option by editing '.resin-sync.yml' directly.
 
-You can save all the options mentioned below in a `resin-sync.yml` file,
-by using the same option names as keys. For example:
+Here is an example '.resin-sync.yml' :
 
-	$ cat $PWD/resin-sync.yml
-	source: src/
+	$ cat $PWD/.resin-sync.yml
+	uuid: 7cf02a6
+	destination: '/usr/src/app'
 	before: 'echo Hello'
+	after: 'echo Done'
 	ignore:
 		- .git
 		- node_modules/
-	progress: true
-	verbose: false
 
-Notice that explicitly passed command options override the ones set in the configuration file.
+Command line options have precedence over the ones saved in '.resin-sync.yml'.
+
+If '.gitignore' is found in the source directory then all explicitly listed files will be
+excluded from the syncing process. You can choose to change this default behavior with the
+'--skip-gitignore' option.
 
 Examples:
 
-	$ resin sync MyApp
-	$ resin sync 7cf02a6
-	$ resin sync 7cf02a6 --port 8080
-	$ resin sync 7cf02a6 --ignore foo,bar
-	$ resin sync 7cf02a6 -v
+	$ resin sync 7cf02a6 --source . --destination /usr/src/app
+	$ resin sync 7cf02a6 -s /home/user/myResinProject -d /usr/src/app --before 'echo Hello' --after 'echo Done'
+	$ resin sync --ignore lib/
+	$ resin sync --verbose false
+	$ resin sync
