+      Pika is powered by the well-tested borg-backup software.
+    </p>
+    <p>
+      <b>Relevant Limitations.</b> Pika currently does not support scheduled backups. Exlcuding files from a backup via regular expressions and alike is not supported yet. Remote backup locations must support SSH and need to have a borg-backup binary installed.
