# Managing Server SDK extensions

The server provides support for any custom extensions that you create using the Server SDK. This chapter summarizes the various features and extensions that can be developed using the Server SDK. Learn more in the [Server SDK documentation](https://developer.pingidentity.com/reference/server-sdk/latest/).

## About the Server SDK

You can create extensions that use the Server SDK to extend the functionality of your server. Extension bundles are installed from a .zip archive or a file system directory. You can use the `manage-extension` tool to install or update any extension that is packaged using the extension bundle format. It opens and loads the extension bundle, confirms the correct extension to install, stops the server if necessary, copies the bundle to the server install root, and then restarts the server.

|   | The `manage-extension` tool can only be used with Java extensions packaged using the extension bundle format. Groovy extensions do not use the extension bundle format. Learn more in [Building and Deploying Java-Based Extensions](https://developer.pingidentity.com/reference/server-sdk/10.2.0.0/getting-started/java-extensions.html) in the Server SDK documentation, which describes the extension bundle format and how to build an extension. |
