+## Code style
+
+We defined to use the following formats:
+- Whitespace Formatting by [Black](https://github.com/psf/black)
+- Docstrings Style see the examples provided by [sphinx napoleon](https://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html) Types in the docstrings are optional but should be consistent per module.
+- Import Order by [isort](https://pycqa.github.io/isort/)
+- Strict Typing of function headers see the examples provided by the [mypy](https://mypy.readthedocs.io/en/stable/cheat_sheet_py3.html) documentation.
+
+## Language
+
+We decided to use english on everything close to code but will write longer texts that are not close to the code in german.
+
+## Pre-Commit installation
+
+- clone the project
+- install the following python package:
+  - `pre-commit`
+
+- execute the command `pre-commit install` to insert the git githook into your local repository.
+  - for more information read [Python Pre-Commit](https://pre-commit.com/)
+  - the following code format rules are so enforced:
+    - Whitespace formatierung:
+      - Python-[Black](https://github.com/psf/black)
+      - leading whitespace in all files
+      - Auto format: yaml, toml, ini
+    - Import norm by:
+      - [isort](https://pycqa.github.io/isort/)
+      - absolut module path
+    - Validierung:
+      - yaml, toml, json, xml
+      - Secret detection
+      - python normen ([pep8](https://peps.python.org/pep-0008/)) with [flake8](https://flake8.pycqa.org/en/latest/)
