Try setting up bors using their public instance (should be all we ever need). Just follow "setting up bors".
Have the build for "staging" and "trying" branches include i-tests.
Don't limit push access to bors only until we're happy with the integration.
Document that we'll be using "bors delegate+" instead of "bors r+" most of the time. See reference.
Include all developers as reviewers in bors settings.
Make a POC on a fork/different repo first and consider if bors can push to non-master branches (we need dev).
