 - 🔒 Ensure your Docker Registry credentials are stored securely as GitHub Secrets
 - 🔄 The workflow will automatically handle the Docker build and push process
 - 🏷️ You can specify any valid Docker tag format in the `tag` input
+- 📤 When `push: true`, the applied tag is also saved as a `docker-image-tag` artifact, so `docker-promote` can promote the exact image CI built for a commit rather than reconstruct its tag
 - 📅 Consider using dynamic tags based on git tags, commit SHAs, or dates
 - 🧪 For testing purposes, you can use the `--dry-run` flag in your own implementation
