1. Wulf can you explain to me how can i create a plugin :) Thank you
     
  2. Well since I saw this here are some things you can use to get started.
    Oxide API Reference - For all the of the hooks/references needed.
    Rust | Oxide - Too look into detail on how they are created and used.
    Solved - Writing C# plugins? | Oxide - This is a overall guide for c# in general.

    Other then that you can contact any plugin dev or anyone that can code with C# or LUA or whatever your language is im sure they will be glad to help!
     
  3. You should download some plugins and look if you can understand what is happening. Then you can make your own plugin using those plugins as example.
