I've worked with developers that went days without committing... it was maddening.
The archive for the git list is at [1].
The other great thing to look for is a well designed standard, with examples, for how a commit message should look. Most everyone who uses a standard uses The Standard* [2], so I would suggest you do the same.
* Except that many projects don't require the sign-off
