+Branches can be created with a simple invocation of \texttt{git-branch}:
+\lstinputlisting[language=bash,numbers=none]{code/5/2}

+\frametitle{\texttt{git-checkout}}
+After the branch is created, we can switch into that branch with
+\texttt{git-checkout}:
+\lstinputlisting[language=bash,numbers=none]{code/5/3}
+\end{frame}
+
+\begin{frame}[fragile]
+\frametitle{\texttt{git-checkout -b}}
+Or, we can do all in the same command:

+\frametitle{Working with remotes}
+\begin{itemize}
+\item{\texttt{git-clone}: Clone ``remote'' repository}
+\begin{itemize}
+\item{\texttt{SSH://}: Bi-directional}
+\item{\texttt{Git://}: Pull only, not authenticated}
+\item{\texttt{HTTP (S)://}: Bi-directional, authenticated, but stupid}
+\item{\texttt{File://}: Strange}
+\end{itemize}
+\item{\texttt{git-push}: Push local changes to remote repository}
+\item{\texttt{git-remote}: Utility command for working with remotes}
+\item{\texttt{git-pull}: Pull remote changes into working copy}

+\frametitle{\texttt{git-pull} considered harmful}
+\begin{itemize}
+\item{Standard use of \texttt{git-pull} requires clean working directory}
+\item{Will force a merge, if drift between remote and local}
+\item{I personally prefer creating an alias for \texttt{git-remote}}
