+    <Link external class="link" href="https://nostr.com/">Nostr</Link> uses "keys" instead of
+    passwords to identify users. This allows users to own their social identity instead of
+    renting it from a tech company, and can bring it with them from app to app.
+  </p>
+  <p>
+    A good way to manage your keys is to use a remote signing application. These apps can hold
+    your keys and log you in remotely to as many applications as you like, without increasing
+    the risk of your keys being stolen.
+  </p>
+  <p>
+    One way to log in with a remote signer is using a "bunker link" which is more secure and
+    decentralized than other solutions. Check your signer for a link beginning with "bunker://",
+    copy it into {PLATFORM_NAME}, and you should be good to go!
+  </p>
+  <p>
+    If you don't have a signer yet, <Link external class="link" href="https://nsec.app/">nsec.app</Link>
+    is an easy way to get started.
