1. Generate xml docs for your project.

   Install godot command line tool (see Godot's Command Line Tutorial for details).

   Export docs for your gdscript to xml via the --doctool flag.

   # Example command to generate docs from scripts in project/scripts to dir doc/my-classes
   godot --path project --doctool doc/my-classes --gdscript-docs res://scripts

2. Use gdxml2yml to generate yml docs for your project. See references section for details on yml schema.

   # You will also need the original xml docs from
   # the godot repo, generate via godot --doctool <path>
   # to generate godot docs at a given path
   #   $ mkdir ref
   #   $ godot --doctool ref
   
   # Generate yml api for docfx.
   # Generates output at folder out/my-classes/api
   # Use the '--filter' flag to only generate docs for your files
   gdxml2yml --filter doc/my-classes doc/my-classes ref out/my-classes/api

3. Use your generated yml in docfx. see the doc/docfx.json for an example. Make sure to include your api folder in the doc content

   {
       "files": ["*.yml"],
       "src": "api",
       "dest": "api"
