 MYPLUGIN PLUGIN WAZ HERE !!
 ```
 
 Wow it worked ! Useless, but worked ! But it's a good demo on how to create your own subcommands in `PowerStencil`.
 
+## Updating zsh auto-completion
+
+When you add a plugin to a project, be it local or from a separated gem, you may want to update the command-line auto-completion for that project as new plugins may add extra command-line options and sub-commands.
+
+You do that as you probably already [dit it initially][completion].
+
+    $ power_stencil adm --zsh-completion

 ## Providing entity types and templates
 
 Of course you can provide new entity types and templates templates within plugin. The plugin created contains a demo entity type which brings its own template template (and even a custom build, but we will see that in next paragraph).
 
 You can see in the output of `power_stencil info` (in _availaible entity types_) that a new entity type has been added to the project by the plugin: `myplugin_entity`
