Git Town committer here. Our commands output the detailed Git commands when they run. In addition, we provide a summary of what each command does in its man page (see
https://github.com/Originate/git-town/blob/master/documentat... for an example).
You have a good point about it being valuable to document the steps run by each command in more detail though. We'll add this, thanks for the suggestion! :)
Btw "git help ship" displays the man page for "git-ship".
