Also cleaned up a little bit of the readme formatting.

This is fantastic @edwardloveall ! I took a break from eject for a few and totally forgot about this. How do I update homebrew when I make a new release?

[edwardloveall]

Pretty simple, just follow the steps here: https://github.com/Homebrew/homebrew-core/blob/26825c7b2dc7aafa9f0ed85af968441ca465e918/CONTRIBUTING.md#submit-a-123-version-upgrade-for-the-foo-formula

Copied here for posterity:

Submit a 1.2.3 version upgrade for the foo formula

• check if the same upgrade has been already submitted by searching the open pull requests for foo.
• brew edit foo
• edit url and sha256/tag, leave the bottle as-is
• brew install --build-from-source foo
• run brew audit --strict foo and fix any issues
• git commit with commit subject foo 1.2.3
• open a pull request and fix any failing tests

Just made a PR with an update. Much more painful than Cocoapods to update, but magic enough.

Yeah they do some weird things. If you don't like their approval process, there's always private taps that you can manage yourself. You could have a raiz tap with all your projects for example.
