Rebooting Deleted My Plugin Work?

I started working on a plugin in the /data/plugins/music_service folder and after rebooting, it was gone. WTF?

To that end, your documentation provides info on layout for plugin development, but does not give information about how to “get started.” Please advise.

Hello,
When starting volumio check the status of plugin. If one is misinstalled it is removed … So don’t work in plugin folder, but copy your files to test from your computer…

Okay, thanks. So, how do I get set up for testing on my computer? I am on a Mac.

please have a look here, a update of the doc explain how to start and avoiding the plugin to be removed
