Subversion (SVN): The Centralized Version Control System

Git won, but Subversion never left, and plenty of long-lived, high-value codebases still run on it. Knowing SVN makes you useful where the code actually lives, and it sharpens your sense of what Git chose and why. This short cursus covers SVN on its own terms: the centralized model with its global revision numbers and atomic commits, the everyday update-edit-commit workflow with conflicts and locking, and branches, tags, and merging built from cheap directory copies, plus how to bridge to Git with git svn.
