             <h1>GrapheneOS releases</h2>
             <p>These releases are available as both tags in the source code repositories and
             official builds.</p>
+            <p>The factory images are used for the initial installation and can be verified with
+            GPG. See the <a href="/install">installation guide</a> for details.</p>
+            <p>GrapheneOS uses automatic over-the-air updates, but full update packages are listed
+            below for uncommon use cases like never connecting the device to the internet. A full
+            update package can upgrade from any past version to the new version. The over-the-air
+            updates use delta update packages when available. Those aren't currently linked below
+            but may be in the future once they're being used more consistently. Update packages
+            are not for performing the initial installation and you should ignore incorrect guides
+            trying to use them to install the OS.</p>
