-    \section{PSA: Update}
+\section{PSA: Update}
+   
+The update of a PSA is basically managed by \href{https://git-scm.com/}{git}, a
+free and open source distributed version control system. Like many other Version
+Control Systems, git has a way to fire off custom scripts when certain important
+actions occur, so-called \href{https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks}{hooks}.
+The hooks used for a PSA update are called {\bf post-checkout} and {\bf post-merge}.\par
+The post-checkout hook is called when checking out some branch of the customer-repository
+(for instance when cloning the customer repository for the first time). In contrast,
+the post-merge hook is called when a \href{https://www.git-scm.com/docs/git-pull}{git pull}
+operation has been issued (more precisely, a \href {https://www.git-scm.com/docs/git-fetch}{git-fetch}
+followed by a \href{https://www.git-scm.com/docs/git-merge}{git-merge}).\par
+Both hooks update the file [{\bf \nameref{updatelogcsv}}], which is interpreted
+by the UpdateController in a second step.
