### Installing and configuring included extensions <a href="#id-.advancedconfigurationv2.x-installingandconfiguringincludedextensions" id="id-.advancedconfigurationv2.x-installingandconfiguringincludedextensions"></a>

Supported extensions, such as those provided by the Keeper Connection Manager packages, are installed through installing their corresponding packages. If you are using [the keeper/guacamole Docker image,](/keeper-connection-manager/installation/docker-compose-install/keeper-guacamole.md) extensions are automatically installed using the above packages depending on the environment variables provided when the container is first started.

The Keeper Connection Manager packages for supported extensions will automatically create symbolic links to install themselves and any needed libraries/drivers. You do not need to manually create links, copy files, etc. for the extensions which are provided within the Keeper Connection Manager repository.

### Custom Extensions

The functionality of Keeper Connection Manager can be extended throught the use of custom extensions. [This page](/keeper-connection-manager/custom-extensions.md) describes how to create a custom extension with examples.
