# Monorepo Guide Roo Code has transitioned to a monorepo powered by [PNPM workspaces](https://pnpm.io/workspaces) and [Turborepo](https://turborepo.com). When you first pull down the monorepo changes from git you'll need to re-install all packages using pnpm. You can install pnpm using [these](https://pnpm.io/installation) instructions. If you're on MacOS the easiest option is to use Homebrew: ```sh brew install pnpm ``` Once pnpm is installed you should wipe out your existing node_modules directories for a fresh start: ```sh # This is optional, but recommended. find . -name node_modules | xargs rm -rvf ``` And then install your packages: ```sh pnpm install ``` If things are in good working order then you should be able to build a vsix and install it in VSCode: ```sh pnpm build --out ../bin/roo-code-main.vsix && \ code --install-extension bin/roo-code-main.vsix ```
