+  <p>
+    <Link external href="https://nostr.com/">Nostr</Link> is way to build social apps that talk to eachother.
+    Users own their social identity instead of renting it from a tech company, and can bring it with them from
+    app to app.
+  </p>
+  <p>
+    This can be a little confusing when you're just getting started, but as long as you're using Flotilla, it
+    will work just like a normal app. When you're ready to start exploring nostr, visit your settings page to
+    learn more.
