In this stream, we implement core pieces of git from scratch by following the CodeCrafters git "course" @ https://app.codecrafters.io/join?via=jonhoo, just like we did for BitTorrent in https://www.youtube.com/watch?v=jf_ddGnum_4.

If you sign up with the link above, you get free access to the challenge (and all their challenges) for 7 days. Alternatively, you can access the content for free (albeit without the nice infrastructure) at https://github.com/codecrafters-io/build-your-own-git.

Video isn't sponsored (as in, I get no money for making the video), though like last time the above _is_ a referral link so that _if_ you find it useful and end up paying that also helps me — maybe a good use for an employee learning budget!
