+
+You can build and run the server using the provided [`Dockerfile`](Dockerfile).
+
+```bash
+# Build the Docker image
+docker build -t google-workspace-mcp .
+
+# Run the Docker container
+# The -p flag maps the container port 8000 to the host port 8000
+# The -v flag mounts the current directory to /app inside the container
+# This is useful for development to pick up code changes without rebuilding
+docker run -p 8000:8000 -v $(pwd):/app google-workspace-mcp
+```
+
+The `smithery.yaml` file is configured to start the server correctly within the Docker container.
