Here's some reading on commit opinions. While I know for our purposes, this can, perhaps, be too verbose, I think there's some good things to think about especially as many people will work in environments with other developers, eventually.
For our Shylock project, consider how you might have gone above just writing 'Act 1,' 'Act 2,' etc. at the end of each prompted section, maybe we could break it down more. While it might seem more tedious, it helps to be explicit and specific. Instead of doing git add ., remember that you can specify which files to add. Be more descriptive with our commit messages.
git add index.htmlgit commit -m 'Act 1 - added form, included scripts for xyz'git add main.js
