Proper use of branches for snap tracks

Hi

I am not clear on how to “correctly” work with tracks. I had imagined that I would use branches in the GitHub repository that contains the snapcraft.yaml definition and that I would be able to connect those branches to the tracks on snapcraft.io. I don’t see how that it is possible though. The builds page seems to only track the default branch of the repository.

What is the suggested workflow for this use case?

Thanks!

Nick
