-Running the Integration Tests
-=============================
-
-These tests require reference files against which the results of the various
-tardis runs are tested. So you first need to either download the current
-reference files (`here <https://github.com/tardis-sn/tardis-refdata>`_)
-or generate new ones.
-
-Both of these require a configuration file for the integration tests:
-
-.. literalinclude:: integration.yml
-    :language: yaml
-
-Inside the atomic data directory there needs to be atomic data for each of
-the setups that are provided in the ``test_integration`` folder.
-If no references are given, the first step is to generate them.
-The ``--less-packets`` option is useful for debugging purposes and will just
-use very few packets to generate the references and thus make the process much
-faster --- THIS IS ONLY FOR DEBUGGING PURPOSES. The ``-s`` option ensures that
-TARDIS prints out the progress:
-
-.. code-block:: shell
-
-    > pytest --integration=integration.yml -m integration --generate-reference --less-packets
-
-To run the test after having run the ``--generate-references``, all that is
-needed is:
-
-.. code-block:: shell
-
-    > pytest --integration=integration.yml -m integration --less-packets --remote-data
+    --tardis-regression-data="/path/to/tardis-regression-data/" --generate-reference
