+
+**Docker is optional.** You can use the GitHub MCP Server without
+installing or running Docker.

+Choose the setup that fits your environment:
+
+- **Hosted server:** Use a supported MCP client with the hosted
+  server and its supported authentication method.
+- **Native execution:** Run a native Go build by following the
+  project's installation instructions.
+- **Docker:** Use the existing Docker setup if you prefer
+  containerized execution.
+
+See the Local GitHub MCP Server section for more details.
