 In this guide, you will learn how to download and configure the Carbyne Stack
 CLI that can be used to interact with a virtual cloud from the command line.
 
+!!! info
+    This guide expects Carbyne Stack to be deployed in a _local_ two player
+    setting using kind clusters as described in the
+    [manual deploymend guide](../deployment/manual). Cluster names as used for
+    connecting to the clusters may be different for individual deployments.

 1. Install the CLI using:
 
     ```shell
     export CLI_VERSION=0.4.1
