 # cds-spreadsheetimporter-plugin
 
 This is a plugin for the [CAP](https://cap.cloud.sap/) framework that allows you to import data from spreadsheets into your CAP project.
+
+## Release Process
+
+This project uses [release-it](https://github.com/release-it/release-it) to automate version management and package publishing. The release workflow is configured through GitHub Actions and can be triggered in two ways:
+
+### Manual Release
+
+1. Go to the GitHub repository's "Actions" tab
+2. Select the "Release" workflow
+3. Click "Run workflow"
+4. You can either:
+   - Leave the version field empty for automatic versioning based on conventional commits
+   - Specify a specific version (e.g., "1.2.0")
+
+### Local Release (for maintainers)
+
+If you prefer to release from your local machine:
+
+1. Ensure you have the necessary credentials:
+   - `NPM_TOKEN` for publishing to npm
+   - `GITHUB_TOKEN` for creating GitHub releases
+2. Run one of the following commands:
+   ```bash
+   npm run release              # For automatic versioning
+   npm run release X.Y.Z        # For specific version
+   ```
+
+### What happens during release?
+
+The release process will:
+
+1. Determine the next version number (based on conventional commits or manual input)
+2. Update the package.json version
+3. Generate/update the CHANGELOG.md file
+4. Create a git tag
+5. Push changes to GitHub
+6. Create a GitHub release with release notes
+7. Publish the package to npm
+
+The release configuration uses the Angular conventional commit preset for changelog generation and requires commit messages to follow the conventional commits specification.
