This document provides an overview of Git and compares its project structure, branching, merging, tagging, and other features to Subversion (SVN). It notes that Git uses a single working directory instead of separate directories for branches like SVN. It outlines how Git handles operations like cloning repositories, branching, merging, tagging, and pushing/pulling changes. The document also discusses common Git commands and how to get help. It includes sections on branching strategies for development, release, and hotfix branches as well as tooling options for Git on the command line, OSX, Windows, and within IDEs like Eclipse and IntelliJ.
