 ## Installation
 Get [Godot](https://godotengine.org/download) and open the src folder as a new project.
 
+## Building and developing with Nix
+### Building
+This project can be build with `$ nix-build` or `$ nix build` (flakes).
+### Building for Linux without Nix
+Use `$ nix bundle`, the resulting binary should be completly self contained.
+### Developing
+It is recommended to use `direnv`, but `$ nix develop`, `$ nix shell` and `$ nix-shell` also work.
