@stuartellis @tombruijn Would it be possible to get a bit of a "mentoring" session from you both, for the people who are serious about helping?
I know you're both pressed for time when it comes to maintaining this project and because of its awesomeness, there's been a few people who have volunteered to help.
But in its present form, the offers for help don't seem to reduce the stress of maintenance on you two, because of what I'm going to summarize as: skilled hands > unskilled hands.
A mentoring session (or two) would cover things along the line of a coding style guide, contribution guidelines (e.g. must pass Travis, must not reduce test coverage more than X percentage points without +1s from Y maintainers), basic issue triage, closing answered or otherwise stale issues, etc.
I know it's a big ask and it might be a slow ramp-up at first, but it would go along way in the sustainability of the project and avoid burning you two out.
