@annakrystalli yes it's now ready!

Given some linters have false positives, for now it's not set up automatically.

[annakrystalli]

Do you just run them manually locally then? If so, should we add a note in the contributing guidelines about it if so so other devs know how to deploy them?

This all looks great to me. I've added my only comment to the PR discussion
