Things To Add
- setup instructions and shell.nix files for languages Godot supports (C#, C/C++, Rust, etc.)
- setup dependencies for exporting to windows, android etc
- how to use the godot_4-export-templates package? godot does not find it when installed. it's easier to use godot to manage it
- superherointj: On export templates: A single "godot_4-export-templates" may be shared between multiple (standard) Godot applications in nixpkgs, and `godot-templates` is required for builds. Added example of usage for `godot-templates` to the Godot wiki page. There is work pending on templates, particularly templates for `godot-mono`. I may look into it eventually.
