Recently I found a nice guide on writing git commits, and I think we
should encourage users to start writing git commits as an explanation
for why changes were made.

This template includes some reference for how long each line should be.
It comes from this Gist (modified to reduce length):
https://gist.github.com/lisawolderiksen/a7b99d94c92c6671181611be1641c733

Explained how Git commits should justify the changes, and added some
details on verbose commits and setting them up.
