+\begin{document}
+\begin{frame}{Warm-up: First things first}
+  \begin{enumerate}
+  \item Install the packages \texttt{git-minimal} and \texttt{which}
+  \item Clone the repository
+    \href{https://gitlab.inria.fr/guix-hpc/open-science-days-tutorial}%
+    {https://gitlab.inria.fr/guix-hpc/open-science-days-tutorial}
+
+    and go inside
+  \end{enumerate}
+\end{frame}
+
+\begin{frame}{Warm-up: Yet another package manager}
+  \begin{enumerate}
+  \item Search with the terms \texttt{high-performance}, \texttt{dynamic},
+    \texttt{language}
+    \item Display the information corresponding to the Julia package
+    \item Install the Julia package and start the Julia REPL (\texttt{julia},
+      quite \emph{Control-D})
+    \item Install other Julia packages: PyPlot and DataFrames
+    \item Try \texttt{guix package -{}-list-generations}
+    \item Remove the package \texttt{julia-pyplot}
+    \item Try \texttt{guix package -{}-roll-back} and list again the generations
+    \item Remove PyPlot and install the Julia packages CSV and Zygote with
+      only one command-line
+    \item Try \texttt{guix package -{}-list-installed}
+  \end{enumerate}
+\end{frame}
+
+\begin{frame}{\texttt{guix shell}}
+  \begin{enumerate}
+  \item Create a shell with the Python packages Python, Pandas, Numpy and
+    Matplotlib
+
+    Start \texttt{python3} and try \texttt{import numpy}
+
+    Exit the created shell with \texttt{exit} or \emph{Control-D}
+  \item Create a manifest file containing these Python packages
+  \item Start a new shell using this manifest file
+
+    Run the script \texttt{python/co2.py}
+
+    Exit the created shell.
+  \item Create a new shell and run the script with one command-line
+  \item Create a new shell using the previous manifest file and start the
+    IPython REPL instead
+
+    Try \texttt{\%run python/co2.py} then \texttt{x.shape}, exit and exit.
+  \item Using the previous manifest, start a new shell using the IPython REPL
+
+    but unsetting all the existing environment variables
+
+    Try \texttt{which ipython}.  Compare with \texttt{echo \$GUIX\_ENVIRONMENT}.
+    Exit.
+  \end{enumerate}
+\end{frame}
+
+\begin{frame}{\texttt{guix shell} again}
+  \begin{enumerate}
+  \item Run the script \texttt{python/co2.py} inside a container.
+
+    Try \texttt{which ipython}.  Try to list other directories.  Exit.
+  \item Create a new shell using the manifest file and using IPython and
+    adding Emacs too
+  \item Idem but containerized.  Start Emacs.  Exit.
+  \item Re-try considering the option \texttt{-{}-network}.
+
+    Try to preserve the environment variable \texttt{TERM} and
+    \texttt{DISPLAY}
+
+    Start Emacs in this container.  Exit.
+  \end{enumerate}
+\end{frame}
+
+\begin{frame}{Example: \texttt{article/the-article.pdf}}
+  \begin{enumerate}
+  \item Try to reproduce the figure
+  \item Try to get the same value (see \texttt{python/co2-bis.py})
+  \end{enumerate}
+  \vfill
+  Bonus: try \texttt{guix lint -c archive python-scikit-learn}
+
+  and browse
