## Development Guide

### Linting

Every commit in the repository is tested with multiple static analyzers.

When developing locally, run some of them using `pre-commit` ([pre-commit docs](https://pre-commit.com/)).

```shell
pre-commit run --all-files
```

That command will check for some issues and automatically reformat the code.
