Great, I see in llm-d-scale that the integration is now showing up correctly behind an experiment.

Let's do two things:

1. is there a logo for llm-d-scale that I can use to replace the generic image?

2. let's work with @mtabasko to start publishing the docs that the integration points to (it's impossible to roll them out exactly at the same time but let's have them land within 1-2 days of each other)
