+        <li><b>Manage multiple BeatSaber versions</b>, designed for people who need to play on different versions or have multiple profiles for the same version.</li>
+        <li><b>Download your maps in the same way</b>, in addition to that, depending on your choice, maps are not version dependent. so you will be able to find your maps whatever version you are using without having to transfer them.</li>
+        <li><b>Install your mods in one click</b>, just like <a href="https://github.com/Assistant/ModAssistant">Mod Assistant</a>, <a href="https://github.com/Zagrios/bs-manager">BSManager</a> will allow you to install your mods quickly and securely depending on the version you choose.</li>
