## Contribution Guide

If you want to work on the volar extension follow these commands to set up your local development environment.

🔎 Note that you will need pnpm - you can download it here: https://pnpm.io/installation.

```bash
git clone https://github.com/vuejs/language-tools.git
cd language-tools
pnpm install
npm run build
```

The recommended way to develop the volar extension is to use the [Debug Tools](https://code.visualstudio.com/Docs/editor/debugging) provided by VSCode.

Alternatively, you can run one of the scripts defined in the [package.json](https://github.com/vuejs/language-tools/blob/master/package.json) file.

❗ You should always use the debug launch configs or package.json scripts defined in the root of the project.

Additional info for contributing to open source projects can be found here: https://docs.github.com/en/get-started/quickstart/contributing-to-projects

To develop with upstream Volar.js modules, you can setup a workspace with https://github.com/volarjs/workspace.
