For information about the agent and how to install it, see the "[Client Part](client-part.html)" topic. - The server is running locally in a Docker container or is accessible on your network For information about the server and how to install it, see the "[Server Part](server-part.html)" topic. - one or more Software Development Kits (SDKs) are installed. For information on installing an SDK, see the "[AGL SDKs](install-sdk.html)" or "[Download or Build Your SDK Installer](../../../../getting_started/reference/getting-started/app-workflow-sdk.html)" topics. - Your XDS configuration is correct. You can test this connection between the agent and the server by opening the XDS Dashboard in a Web Browser and confirming no error messages.
