<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>
