• Revisit "shebang"
  • move to "advanced?"
  • deduplicate with "usage"

@blakeembrey I updated the website publishing to publish from this branch instead of main. I also have the README on this branch rendering from the website's MD files.

When I'm done with all the TODOs, this will definitely need a review to make sure it's intuitive to people who are not intimately involved with the project. I'm cautiously optimistic that these changes will be well-received, but I'm also wary of changing too much and accidentally making some things confusing.
