-## Code style guide
-
-We use the `camelCase` to more easily differentiates our functions from the ones
-from PTB that use a `PascalCase`.
-
-In practice, we use the following regular expression for function names:
-`[a-z]+(([A-Z]|[0-9]){1}[a-z]+)*`.
-
-> Regular expressions look scary but are SUPER useful to sort through filenames:
->
-> -   A quick [intro to regular expression](https://www.rexegg.com/)
->
-> -   And many websites allow you to "design and test" your regular expression:
->     -   [regexper](https://regexper.com/#%5Ba-z%5D%2B%28%28%5BA-Z%5D%7C%5B0-9%5D%29%7B1%7D%5Ba-z%5D%2B%29)
->     -   ...
-
-We keep the McCabe complexity below 15 as reported by the
-[check_my_code function](https://github.com/Remi-Gau/check_my_code) or the
-[MISS_HIT code checker](https://florianschanda.github.io/miss_hit). A couple of
-code quality metrics are also checked automatically by MISS_HIT (avoiding
-functions with too many nested `if` blocks).
-
-We use the
-[MISS_HIT linter](https://florianschanda.github.io/miss_hit/style_checker.html)
-to automatically fix some linting issues.
-
-The code style and quality is also checked during the
-[continuous integration](.github/workflows/miss_hit.yml).
+## Contributing
 
-## Unit tests
+Feel free to open issues to report a bug and ask for improvements.
 
-Unit tests are run with the mox unit toolbox and automated with github action on
-Octave.
+If you want to contribute, have a look at our
+[contributing guidelines](https://github.com/cpp-lln-lab/.github/blob/main/CONTRIBUTING.md)
+that are meant to guide you and help you get started. If something is not clear
+or you get stuck: it is more likely we did not do good enough a job at
+explaining things. So do not hesitate to open an issue, just to ask for
+clarification.
