          <h2>What is HoloISO?</h2>

<blockquote><em>[HoloISO] attempts to bring the Steam Deck&#39;s SteamOS Holo into a generic, installable format, and provide a close-to-official SteamOS experience. Main point of this project focuses in re-implementing proprietary (as in runs-only-on-deck) components that Steam client, OS itself, gamescope and user-created applications for Deck rely on. -<a href="https://github.com/theVakhovskeIsTaken/holoiso" target="_blank">https://github.com/theVakhovskeIsTaken/holoiso</a> </em></blockquote>
