Download pre-built binaries from the [GitHub Releases page](https://github.com/helix-editor/helix/releases).
Add the `hx` binary to your system's `$PATH` to use it from the command line, and copy the `runtime` directory into the config directory (for example `~/.config/helix/runtime` on Linux/macOS).
The runtime location can be overriden via the HELIX_RUNTIME environment variable.
