<p>A <a href="https://nixos.wiki/wiki/Flakes">flake</a> containing the package is available in

<pre><code>git clone --recurse-submodules --shallow-submodules -j8 https://github.com/helix-editor/helix
cd helix
cargo install --path helix-term
</code></pre>
<p>This will install the <code>hx</code> binary to <code>$HOME/.cargo/bin</code>.</p>
<p>Now copy the <code>runtime/</code> directory somewhere. Helix will by default look for the
runtime inside the same folder as the executable, but that can be overriden via
the <code>HELIX_RUNTIME</code> environment variable.</p>
