 - **Import JavaScript modules from `vite-plus`:** Instead of importing from `vite` or `vitest`, all modules should be imported from the project's `vite-plus` dependency. For example, `import { defineConfig } from 'vite-plus';` or `import { expect, test, vi } from 'vite-plus/test';`. You must not install `vitest` to import test utilities.
 - **Type-Aware Linting:** There is no need to install `oxlint-tsgolint`, `vp lint --type-aware` works out of the box.
 
+## CI Integration
+
+For GitHub Actions, consider using [`voidzero-dev/setup-vp`](https://github.com/voidzero-dev/setup-vp) to replace separate `actions/setup-node`, package-manager setup, cache, and install steps with a single action.
+
+```yaml
+- uses: voidzero-dev/setup-vp@v1
+  with:
+    cache: true
+- run: vp check
+- run: vp test
+```

 ## Review Checklist for Agents
