This will install the `hx` binary to `$HOME/.cargo/bin`.
Helix also needs its runtime files so make sure to copy/symlink the `runtime/` directory into the
config directory (for example `~/.config/helix/runtime` on Linux/macOS). This location can be overriden
via the `HELIX_RUNTIME` environment variable.
config directory (for example `~/.config/helix/runtime` on Linux/macOS, or `%AppData%/helix/runtime` on Windows).
This location can be overriden via the `HELIX_RUNTIME` environment variable.
Packages already solve this for you by wrapping the `hx` binary with a wrapper
that sets the variable to the install dir.

# 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](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 guidelines can be found [here](./docs/CONTRIBUTING.md).

## Queries
For a language to have syntax-highlighting and indentation among other things, you have to add queries. Add a directory for your language with the path `runtime/queries/<name>/`. The tree-sitter [website](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries) gives more info on how to write queries.
