2. Create a local directory (e.g. /home/user/deflex_examples).
3. Browse the `examples <https://osf.io/9krgp/files/>`_ for deflex v0.4.x or
   download all examples as `zip file <https://files.de-1.osf.io/v1/resources/9krgp/providers/osfstorage/620b67ed11da1c0120f56939/?zip=>`_ and copy/extract them to your local directory.
4. Read the comments of each example, execute it and modify it to your needs.
   Do not forget to set a local path in the examples if needed.
5. In parallel you should read the ``usage guide`` of the documentation to get

**Figure 3:** The resulting system costs of deflex have been compared with the
day-ahead prices from the Entso-e downloaded from `Open Power System Data
<https://open-power-system-data.org/>`_. The plot shows three different periods
of the year.

**Figure 4:** It is also possible to get a time series of the average emissions. Furthermore,
it shows the emissions of the most expensive power plant which would be
replaced by an additional feed-in.

**Figure 5:** The following plot shows fraction of the time on which the utilisation of the
power lines between the regions is more than 90% of its maximum capacity:
