# `@pierre/diffs`

Modified by Palot contributors for Palot-specific scope and Vite+ installation
guidance. See [NOTICE.md](NOTICE.md) for the pinned upstream source and
[LICENSE.md](LICENSE.md) for the Apache-2.0 license.

Use `@pierre/diffs` to render syntax-highlighted files and diffs. Use its
optional editor, SSR, and worker entries for those capabilities.

## Install

```bash
vp add @pierre/diffs
```

Run the install command from `apps/desktop`. Install `react` and `react-dom` when the app uses the React entry.
