Numbered branches (0 and up) have the most up-to-date code (often newer than the most recent published revision of the book). When code has changed between book revisions, a new code version is created, and each branch is tagged, with the naming format [step]_[version]. For instance, revision r6 of the book was published with version 1.0.0 of this repo, so the tag for step 2 was 2_1.0.0.

Thank you to everyone who has contributed 😃🙌
We welcome issues and PRs! For large changes, we recommend opening an issue first to get feedback before putting in the work of a PR. Minor things like typo fixes can go directly to PRs and will usually get a quick response 😊
When editing code that's part of the book, submit the PR to the corresponding step branch (eg branch 3 for step 3) instead of to master.
