- We recently changed the name of the Linux commands tap from
  Linuxbrew/homebrew-developer to Homebrew/homebrew-linux-dev in our
  continual efforts to move away from the Linuxbrew name. Related to
  this, we changed the comment produced by `brew build-bottle-pr` to
  simply "Linux".
- We also [changed `brew
  find-formulae-to-bottle`](https://github.com/Homebrew/homebrew-linux-dev/pull/130)
  so that it will build a bottle for a formula even if it has a macOS
  requirement. There were cases like `go` that build perfectly fine on
  Linux.

- Also document some things that could go wrong and how to recover from
  them.

- There are a lot more manual steps in Homebrew on Linux (Linuxbrew)
  land than there are in Homebrew (core), it feels like.
- This is a first attempt at a maintainer's guide. I have basically
  tried to brain-dump everything that Michka and Shaun have taught me
  over the months into something consumable for future Homebrew on Linux
  maintainers!
- Some of it is overly verbose - the merging docs are taken from
  [Linuxbrew/homebrew-developer's docs](https://github.com/Linuxbrew/homebrew-developer/blob/master/docs/merge-homebrew-core.md)
  which were recently updated to reflect reality but probably don't need
  to have so many words: just some instructions. :-)
