@StevenClontz I've clarified what it means to be an almost 2-star refinement. Do you agree with the changes?

Thanks for the fixes @Moniker1998!

FYI, when you do a "squash and merge", it is recommended to first blank out the associated description before clicking on "squash and merge". I.e., only keep the title.

and by the way, Steven is now kind of ok with doing this, right?

I'm still not 100% sold on the utility of it (and this week I'm hacking on a project where we don't do that step, so I'm getting confused on which workflow I'm using lol) but I've started doing it here. We can discuss at a future meeting.
