Polish mod5 content for publishing

[kianenigma]

This addresses some of the low hanging fruit TODOs in my slides, and any immediately actionabel item in #761.

Lots more can be done, but I think this is all that's needed before going public with regard to the slides.

LGTM! Thanks for doing this! We will want to followup with a conventions shift on where files live and how they are named, but this is a great polish on what actually matters: the content :)
