    - Install packages and use isolated environments
+
       - With a virtual environment you can tailor an environment with specific versions for Python and packages, not interfering with other installed python versions and packages.
       - Make it for each project you have for reproducibility.
       - There are different tools to create virtual environments.
-         - ``virtualenv`` and ``venv``
+
+         - ``venv``
             - install packages with ``pip``.
             - the flag ``--system-site-packages`` includes preinstalled packages as well
-      - Conda (available everywhere but not HPC2N)
-         - Conda is an installer of packages but also bigger toolkits

+   - Slurm and batch
+
+       - The SLURM scheduler handles allocations to the calculation nodes
+       - Batch jobs runs without interaction with user
+       - A batch script consists of a part with *SLURM parameters* describing the allocation and a second part describing the actual work within the job, for instance one or several Python scripts.
+       - Remember to include possible input arguments to the Python script in the batch script.
 
    - Interactive work on calculation nodes
+
       - Start an interactive session on a calculation node by a SLURM allocation (similar flags)
