-# Contributing
-
-Like with all FS projects, you are welcome to contribute. Work is done usually by the person that is most annoyed
-by the circumstances or by the person that didn't run fast enough. So we are happy if we get help. That doesn't
-mean that we don't need to have some level of quality, people after us needs to work with it. It is live infrastructure
-and downtime hurts someone (and in the wrong moment even really bad (Matheball ticket sales for example).
-
-So here are some Guidelines.
-
-## Coding style and linting.
-If you run `nix check` there are automated checks in place, please make sure to pass them.
-There is also a code autoformatter (`alejandra`) incorporated into those. You can also install
-them into your local git repository as pre-commit hooks, and setting up a shell that has
-even more tooling by running `nix develop`. That will give you a bash in which you can run
-all the checks manually `pre-commit run -a`. This will also run the autoformatter.
-
-## Process for submitting changes
-
-1. If it is something bigger, please open an issue first describing what and why you want to do something.
-   If it is just something small, skip this step.
-2. Fork the repo and implement your changes in a branch on your fork. Afterwards open a pull request (possibly mentioning the issue).
-   Against the main branch.
-   - Your branch should be based on an up to date version of main, if it is not consider rebasing.
-3. You will need to find someone with the proper rights to approve of your changes, but most of the time there will be request
-   for changes first.
