 # Contributing
 
+Please review our more detailed [Coding Guidelines](https://alpaka.readthedocs.io/en/latest/dev/style.html) as well.
+
+## Pre-commit
+
+This project is set up for use with [pre-commit](https://pre-commit.com). Using it will make your code conform with most
+of our (easily automatable) code style guidelines automatically.
+In very short (for anything further see [pre-commit](https://pre-commit.com)), after running the following in your
+working clone of alpaka
+```bash
+# if not yet done, install the pre-commit executable following https://pre-commit.com
+cd /path/to/alpaka-working-clone
+pre-commit install
+```
+`git` will run a number of checks prior to every commit and push and will refuse to perform the
+pertinent action if they fail. Most of them (like e.g. the formatter) will have automatically altered your working tree
+with the necessary changes such that
+```bash
+git add -u
+```
+will make the next commit pass.
+
 ## Formatting
 
-Please format your code before before opening pull requests using clang-format 16 and the .clang-format file placed in the repository root.
+Please format your code before before opening pull requests using clang-format 16 and the .clang-format file placed in 
+the repository root. If you were using `pre-commit` during your changes, this has happened automatically already. If
+not, find further instructions below.
 
 ### Visual Studio and CLion
-Suport for clang-format is built-in since Visual Studio 2017 15.7 and CLion 2019.1.
+Support for clang-format is built-in since Visual Studio 2017 15.7 and CLion 2019.1.
 The .clang-format file in the repository will be automatically detected and formatting is done as you type, or triggered when pressing the format hotkey.
