+### Authenticating with the Authorization server
+Authenticating with the authorization server is simplified through the use of a helm plugin, `zoraauth`, which can be installed by executing
+
+```console
+helm plugin install https://github.com/undistro/helm-zoraauth
+```
+and updated by executing
+```console
+helm plugin update zoraauth
+```
+The authentication process will occur when the plugin is executed, and you visit the authorization server to confirm the request.  The instructions within the Zora Dashboard console will include the appropriate parameters for the plugin, these can be obtained through the `Connect cluster` option once you have signed in to the Zora Dashboard.
+
+To authenticate with the authorization server, copy and run the `helm zoraauth` command and then follow the instructions within your terminal
+```console
+helm zoraauth --audience="zora_prod" \
+  --client-id="<client id>" \
+  --domain="login.undistro.io"
+Initiating Device Authorization Flow...
+Please visit https://login.undistro.io/activate and enter code: BFNS-NWFF, or visit: https://login.undistro.io/activate?user_code=BFNS-NWFF
+```
+Entering the login URL within your browser will present you with a screen similar to the following
