Beej's Guide to Git

I can't help but feel that Git has completely missed the forest through the trees that you can make a 30+ part guide explaining how to use it.

My sense, bluntly, is that if people spent half the effort learning git that they do whining about it, no one would bother making a 30+ part guide just explaining stuff you could find in a man page.

Commits are snapshots of a tree. They have a list of ancestors (usually, but not always, just one). Tags are named pointers to a commit that don't change. Branches are named pointers to a commit that do change. The index is a tiny proto-commit still in progress that you "add" to before committing.

There. That's git. Want to know more? Don't read the guide, just google "how to I switch to a specific git commit without affecting my tree?", or "how do I commit only some of my changed files?", or "how to I copy this commit from another place into my current tree?".

The base abstractions are minimalist and easy. The things you want to do with them are elaborate and complicated. Learn the former, google the latter. Don't read guides.
