+### Credentials
+Since this tries to run in an isolated network we can't rely on autodiscover and the spotify client needs to be tied to an account.
+
+This is achieved by registering the client on startup via oauth. The logs show an url which should be copied to a local browser. The successfull redirect needs to be forwarded back to the client, hence run:
+```
+k port-forward deployments/snapcast 5588:5588
+```
