+## Development environment
+
+Prerequisite: [Nix](https://nixos.org/download/)
+
+When entering the project directory, run `nix-shell` to activate the development environment.
+
+On initial use, and when `package-lock.json` changes, run `npm i` to install Node.js packages. This will create a `node` executable in the root of the repo which you can use as the IDE interpreter.
