+\subsubsection*{Local configuration.}
+First, let Git know what your name and e-mail address is:
+\begin{lstlisting}
+  $ git config --global user.name "<Your Name>"
+  $ git config --global user.email "<name@lumc.nl>"
+\end{lstlisting}
+\bigskip
+
+Check whether you have an ssh key:
+\begin{lstlisting}
+  $ cat ~/.ssh/id_rsa.pub
+\end{lstlisting}
+\bigskip
+
+If not, make one:
+\begin{lstlisting}
+  $ ssh-keygen
+  Enter file in which to save the key (/home/<username>/.ssh/id_rsa):
+  Enter passphrase (empty for no passphrase):
+  Enter same passphrase again:
+\end{lstlisting}
+You can leave all fields blank.
+
+\subsubsection*{Remote configuration.}
+Open \texttt{https://git.lumc.nl} in your browser.
+\bigskip
+
+In the authentication form, use your LUMC username and password (LDAP login).
+\bigskip
+
+You can now edit your profile by clicking on the ``profile'' button (pictogram
+of a torso), located on the top right of your screen. On mouse over, a text
+balloon will pop up, saying ``My profile''.
+\bigskip
+
+Check your name and e-mail address (you probably want to change your name).
+\bigskip
+
+To be able to upload new versions, you need to add your ssh key. Click the
+``Add Public Key'' button.
+
+Give your key a title (e.g., ``Course Laptop'').
+
+Copy your ssh key to the key field (see the \texttt{cat} command above).
