 \begin{itemize}
 
+\item Create a branch based on a remote tree to explore a particular

 \item Explore the sources in search for files, function headers or
   other kinds of information...
 \item Browse the kernel sources with tools like \code{cscope} and LXR.

+Let's work with a particular stable version of the Linux kernel.
+It would have been more logical to do this in the previous lab, but we
+wanted to get back to lectures while the \code{fetch} command was
+running.
+
+First, let's get the list of branches on our \code{stable} remote tree:
+
+\begin{verbatim}
+cd ~/felabs/linux/src/linux
+git branch -a
+\end{verbatim} 
+
+As we want to work with the Linux 3.11 stable branch, the remote branch
+we are interested in is \code{remotes/stable/linux-3.11.y}.
+
+First, open the \code{Makefile} file just to check the Linux kernel
+version that you currently have.
+
+Now, let's create a local branch starting from that remote branch:
+\begin{verbatim}
+git checkout -b 3.11.y stable/linux-3.11.y
+\end{verbatim} 
+
+Open \code{Makefile} again and make sure you now have a 3.11.y version.
