-            <p>Partial list of GrapheneOS features:</p>
+            <p>GrapheneOS is based on the Android 11 release of the Android Open Source Project
+            which provides a strong baseline for privacy and security. GrapheneOS takes great care
+            to preserve the baseline privacy and security, including taking full advantage of all
+            of the standard hardware features. The privacy and security features inherited from
+            AOSP and the hardware are not covered here. Documentation on that will be gradually
+            added elsewhere on our site.</p>
