Improve build documentation

[knickels]

I'm adding my notes as I do this build. Does it make sense to batch them into a single PR?

These are great additions as is - appreciate your contributions!
Smaller, frequent PRs tend to work better and mean that if one PR is stuck in review, other changes can make it in faster.
@abust005 @apollokit any comments or good to merge?

Good changes, I say good to merge. Glad that some of the TODOs are gone, I hadn't even noticed them (highway blindness, I guess)

I see the docs/readthedocs.org job failed, but it looks like an upstream config issue. Is that something I need to worry about?

[knickels]

Marking as ready for review. I've finished with the harnesses and the motor board build.

Thank you!
The readthedocs build task failure is unrelated. It is due for an update but low priority since few people seem to use it.
