Add company Logo and favicon

We have the free tier of Metabase running in a Docker container inside a AWS Linux EC2 instance. In the Metabase documentation (Customer-facing analytics) I see that we can add our company logo instead of the Metabase logo:

But is not clear how I would go about this. Is this something I can change in the interface in Admin Settings or do i need to get it into the docker container?

I don't think that's available in the free edition. You need to go Pro.
