+Installation
+============
+
+The snapstore client can be installed from the snap store:
+
+    snap install snapstore-client
+
+Configuration
+=============
+
+The client requires an admin user to be registered in the Snap Enterprise Proxy
+before it can perform any operations. This user must be registered with
+the [Ubuntu SSO provider](https://login.ubuntu.com).
+
+From the command line on the machine that has the Proxy installed, run:
+
+    sudo snapstore add-admin [e-mail]
+
+Once the user has been registered, the client can login:
+
+    snapstore-client login
+
+Usage
+=====
+
+snapstore-client provides the same command line interface for managing overrides
+as the CLI client installed with the Proxy. It cannot configure any system
+settings for the Proxy.
+
+    snapstore-client list-overrides
+    snapstore-client override foo stable=10
+    snapstore-client delete-override foo
