+	Git is a version control system that allows tracking changes in files within a directory.
+	It is mainly used for source code management in software development. However, many of us
+	also use it for writing texts in \LaTeX. Besides tracking history, Git facilitates
+	merging changes when multiple people edit the same files simultaneously. We will look at
+	how Git works. We will describe how Git uses \emph{hash functions}, \emph{Merkle trees},
+	and \emph{directed acyclic graphs} to store version history and facilitate concurrent
+	content editing. The mathematical model used by Git is actually very simple, and
+	understanding it can save us many headaches during its use.
