@ -78,6 +78,9 @@ Some suggestions to get started:
- You can look at the [good first issue](https://github.com/helix-editor/helix/labels/good%20first%20issue) label on the issue tracker.
- Help with packaging on various distributions needed!
- To use print debugging to the `~/.cache/helix/helix.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.
