+### Nix Flake
+
+A `flake.nix` is provided for [Nix](https://nixos.org/) users:
+
+```sh
+nix develop        # Enter dev shell with all dependencies
+pnpm install       # Install npm packages
+pnpm build         # Build the project
+pnpm test          # Run tests
+pnpm vsix          # Create VSIX package
+```
+
+To build and install the extension directly:
+
+```sh
+nix build .#vsix && code --install-extension result/*.vsix
+```
+
+The dev shell provides Node.js 20.x, pnpm, ripgrep, and build tools for native modules.
+
+After updating dependencies, run `nix run .#update-deps` to update `flake.lock` and the pnpm dependency hash.
+
+If flakes aren't enabled, prefix commands with: `nix --extra-experimental-features 'nix-command flakes' <command>`
+
+> **Note:** Roo Code is also available as a pre-built extension in [nixpkgs](https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/applications/editors/vscode/extensions/rooveterinaryinc.roo-cline/default.nix) via `vscode-extensions.rooveterinaryinc.roo-cline`.
