How Git Works by Julia Evans

You use Git every day, but are there still times when it scares you? When a `git push` is rejected, when a colleague says, "Please rebase and upload," or when that "detached HEAD state" message pops up. You’ve probably had at least one moment where your mind went blank, and you ended up deleting the entire folder just to clone it again. This course is for people like you. Julia Evans' 〈How Git Works〉, beloved by developers worldwide, is finally available in Korean. This isn't a course about memorizing commands. It’s a course where we take a slow, deep look at how Git actually works under the hood. What’s inside the `.git` folder, How branches are actually stored, Where "orphaned" commits go and how to recover them, And what "up to date with origin/main" actually means. It consists of 27 pages across 6 chapters: ★ Commits ★ Branches ★ Exploring the .git folder ★ Merging ★ Remote repositories ★ Surviving disasters Once you properly grasp the internal model, you'll be able to interpret any message Git throws at you on your own. Instead of memorizing commands, you'll start using it while understanding "why it works this way." I’ll share the promise Julia made on the first page of her zine: "Once you understand the internals, you can get yourself out of any Git mess."
