+
+## Dockerization and Continuous Integration
+
+#### Docker Images
+AppFlowy leverages Docker for efficient deployment and scaling. Docker images are available at:
+- `appflowy_cloud`: [Docker Hub](https://hub.docker.com/repository/docker/appflowyinc/appflowy_cloud/general)
+- `admin_frontend`: [Docker Hub](https://hub.docker.com/repository/docker/appflowyinc/admin_frontend/general)
+
+#### Automated Builds with GitHub Tags
+The Docker images are automatically built and updated through a GitHub Actions workflow:
+
+1. **Tag Creation**: A new tag in the GitHub repository indicates a new version or release.
+2. **Automated Build Trigger**: This tag initiates the Docker image building process via GitHub Actions.
+3. **Docker Hub Updates**: The `appflowy_cloud` and `admin_frontend` images are updated on Docker Hub with the latest build.
