Commissioning the Majorana Demonstrator

The \textsc{Majorana} \textsc{Demonstrator} deploys high purity germanium (HPGe) detector modules to search for neutrinoless double beta (0$\nu\beta\beta$) decay in $^{76}$Ge. The experiment is aimed at demonstrating the technical feasibility and low backgrounds for a next generation Ge-based \BBz\ experiment. The program of testing and commissioning the \textsc{Demonstrator} modules is a critical step to debug and improve the experimental apparatus, to establish and refine operational procedures, and to develop data analysis tools. In this talk, we will discuss our experience commissioning the \textsc{Demonstrator} modules and show how this program leads to successful data-taking.
