-A good start to contribute is an enhancement of existing code with better or new functions. To respect a common coding style, Birdhouse uses PEP8_ checks to ensure a consistent coding style. Currently the following PEP8 rules are enabled in ``setup.cfg``:
-
-.. code-block:: ini
-
-   [flake8]
-   ignore=F401,E402
-   max-line-length=120
-   exclude=tests
-
-See the flake8_ documentation on how to configure further options.

-To check the coding style run ``flake8``:
-
-.. code-block:: sh
-
-    $ flake8 emu   # emu is the folder with python code
-    # or
-    $ make pep8    # make calls flake8
-
-To make it easier to write code according to the PEP8 rules enable PEP8 checking in your editor. In the following we give examples how to enable code checking for different editors.

 A Process is calling several functions during the performance. Since WPS is a autonom running process several eventualities needs to be taken into account. If irregularities are occurring, it is a question of the process design if the performance should stop and return an error or continue with may be an modified result.
 
 In practice, the functions should be encapsulated in **try** and **except** calls and appropriate information given to the logfile or shown as a status message. The logger has several options to to influence the running code and the information writing to the logfile:
