 ## Development
-### Code Style
+Please refer to our [development wiki](https://flaschengeist.dev/Flaschengeist/flaschengeist/wiki/Development).
-We enforce you to use PEP 8 code style with a line length of 120 as used by Black.
-See also [Black Code Style](https://github.com/psf/black/blob/master/docs/the_black_code_style.md).
-
-#### Code formatting
-We use [Black](https://github.com/psf/black) as the code formatter.
-
-Installation:
-
-    pip install black
-Usage:
-
-    black -l 120 DIRECTORY_OR_FILE
-
-### Misc
-#### Git blame
-When using `git blame` use this to ignore the code formatting commits:
-
-    $ git blame FILE.py --ignore-revs-file .git-blame-ignore-revs
-Or if you just want to use `git blame`, configure git like this:
-
-    $ git config blame.ignoreRevsFile .git-blame-ignore-revs
-
-#### Ignore changes on config
-    git update-index --assume-unchanged flaschengeist/flaschengeist.toml
