<ul>
<li>SteamVR must be installed and working with your headset before launching</li>
<li>Your VR runtime (SteamVR, ALVR, WiVRn, etc.) must be configured separately</li>
<li>Some modlists may require additional manual steps documented by the list author</li>
</ul>

<p>Jackify's VR support is <strong>best effort</strong>. The install and configuration will proceed normally, but whether the modlist runs correctly depends heavily on your VR platform setup.</p>

<p><strong>Always consult your modlist's installation guide</strong> for any additional manual steps required after Jackify completes.</p>
