+## Options `with: ...`
+
+- `install_url`: specify URL to install Nix from (mostly useful for testing non-stable releases)
+
+- `nix_path`: set `NIX_PATH` environment variable (if set `skip_adding_nixpkgs_channel` will be implicitly enabled)
+
+- `skip_adding_nixpkgs_channel`: set to `true` to skip adding nixpkgs-unstable channel (and save ~5s for each job build)
