+### Building
+
+The action uses [@vercel/ncc](https://github.com/vercel/ncc) to compile the code and dependencies into a single file. This eliminates the need to commit `node_modules`.
+
+```bash
+npm run build
+```
+
+This creates a `dist/index.js` file that includes all dependencies bundled together.
