+### Authentication for GitHub Packages
+
+To access GitHub Packages, you need to authenticate with GitHub. You can do this by:
+
+1. **Using environment variables:**
+   ```bash
+   export USERNAME=your_github_username
+   export TOKEN=your_github_personal_access_token
+   ```
+
+2. **Using gradle.properties:**
+   ```properties
+   gpr.user=your_github_username
+   gpr.key=your_github_personal_access_token
+   ```
+
+You can generate a personal access token at [GitHub > Settings > Developer settings > Personal access tokens](https://github.com/settings/tokens) with `read:packages` permission.
