(Hi! Thanks, nice looking tool. Just a very minor incongruity I figured I'd mention in case it's useful)
The setup instructions say:
Set the repo to only support merge commits
But the screenshot shown just below show the opposite, checking only squash merges:

I don't personally generally recommend doing that in a git repo, but if there's some reason why landscapes really do need to always merge using squash then probably the simple fix is to just tweak the text above to say "squash merge" rather than "merge". Happy to send a PR if so, but filing this first since I wasn't sure which is actually correct, the text or the image, or whether really this step isn't actually required.
