# Contributing # Contributing
Contributors are very welcome! **No contribution is too small and all contributions are valued.** Contributing guidelines can be found [here](./docs/CONTRIBUTING.md).
Some suggestions to get started:
- You can look at the [good first issue](https://github.com/helix-editor/helix/issues?q=is%3Aopen+label%3AE-easy+label%3AE-good-first-issue) label on the issue tracker.
- Help with packaging on various distributions needed!
- To use print debugging to the [Helix log file](https://github.com/helix-editor/helix/wiki/FAQ#access-the-log-file), you must:
* Print using `log::info!`, `warn!`, or `error!`. (`log::info!("helix!")`)
* Pass the appropriate verbosity level option for the desired log level. (`hx -v <file>` for info, more `v`s for higher severity inclusive)
- If your preferred language is missing, integrating a tree-sitter grammar for
it and defining syntax highlight queries for it is straight forward and
doesn't require much knowledge of the internals.
We provide an [architecture.md](./docs/architecture.md) that should give you
a good overview of the internals.

# Contributing
Contributors are very welcome! **No contribution is too small and all contributions are valued.**
Some suggestions to get started:
- You can look at the [good first issue][good-first-issue] label on the issue tracker.
- Help with packaging on various distributions needed!
- To use print debugging to the [Helix log file][log-file], you must:
* Print using `log::info!`, `warn!`, or `error!`. (`log::info!("helix!")`)
* Pass the appropriate verbosity level option for the desired log level. (`hx -v <file>` for info, more `v`s for higher severity inclusive)
- If your preferred language is missing, integrating a tree-sitter grammar for
it and defining syntax highlight queries for it is straight forward and
doesn't require much knowledge of the internals.
We provide an [architecture.md][architecture.md] that should give you
a good overview of the internals.
# Auto generated documentation
Some parts of [the book][docs] are autogenerated from the code itself,
like the list of `:commands` and supported languages. To generate these
files, run
```shell
cargo xtask docgen
```
inside the project. We use [xtask][xtask] as an ad-hoc task runner and
thus do not require any dependencies other than `cargo` (You don't have
to `cargo install` anything either).
