Overview

Fixes a few small inconsistencies in docs / TS templates. Should be self-explanatory, but I'm happy to explain any that are unclear.

Once I finish reading the book, I'll probably do a pass to ensure the comments at the top of each index.ts match what the README is asking for; I've just been filing these as I found them.

Also if I want to get in the "All Contributors" section (assuming I qualify), do I edit that file manually or go through a bot? CONTRIBUTING.md was unclear on that point.

Thanks!

Separately, do you have a preferred avenue for typos in the text of the book itself? I found a small one but didn't see a place to fix it.

Good point, that should be documented.

We can ignore the test failures, they're unrelated. I'll look into them if I have time or someone reports them explicitly. It's some oddity with shell scripting in the verify-everything-has-changed-properly CI setup.

Great! Yes, there is an errata & submissions section on the O'Reilly site: https://www.oreilly.com/catalog/errata.csp?isbn=0636920578000
