Hi,

I have very little knowledge of how Discourse works but I need to create a plugin. I’ve seen the different Guides on how to create a plugin like [Developing Discourse Plugins - Part 1 - Create a basic plugin](https://meta.discourse.org/t/beginners-guide-to-creating-discourse-plugins-part-1/30515) or [Rails plugin generator](https://meta.discourse.org/t/rails-plugin-generator/95907).

1. I don’t know how to find the “plugins” directory ? I’ve looked under /var/discourse/ and /var/lib/docker/ but I can’t find the one that is used by Discourse.

2. I don’t understand how to use the Rails plugin generator.

`rails g plugin DiscourseRacoon`

I’m trying to use this command but I always have this result

```
root@discourse:~# rails g plugin testPLugin
Usage:
  rails new APP_PATH [options]
Options:
  -r, [--ruby=PATH] # Path to the Ruby binary of your choice

```

I’ve tried to look for answers on how those commands and on how Discourse works but I can’t find any.  
I hope I’ve been clear on what I’m searching for and thanks for any answer
