How to create documentation for a Godot Module

godot_module_docs.md

So after fiddling and experimenting, I kinda figured out the workflow of writing custom docs for your custom module :D

1. Make a new directory doc_classes in the root of your custom module.

2. Add following code to config.py:

   def get_doc_classes(): return [ "YourClassName", ]

   def get_doc_path(): return "doc_classes"

3. Run command line godot --doctool <godot_build_path>

4. Get generated doc file from godot\doc\classes\YourClassName.xml

5. Copy this file to doc_classes and edit it.

If you build again, the build system will get the doc from doc_classes instead of generating a new one.(edited)
