+    Open source RGB lighting control that doesn't depend on manufacturer
+    software.
+  </summary>
+
+  <description>
+    <p>
+      One of the biggest complaints about RGB is the software ecosystem
+      surrounding it.  Every manufacturer has their own app, their own brand,
+      their own style.  If you want to mix and match devices, you end up with a
+      ton of conflicting, functionally identical apps competing for your
+      background resources.  On top of that, these apps are proprietary and
+      Windows-only.  Some even require online accounts.  What if there was a way
+      to control all of your RGB devices from a single app, on both Windows and
+      Linux, without any nonsense?  That is what OpenRGB sets out to achieve.
+      One app to rule them all.
