+    <p>The app can be downloaded in two ways:</p>
+    <ul>
+        <li>Google Play Store: The easiest method, search for "Fallback" and install the app from there.</li>
+        <li>Github Releases: For those who cannot or do not want to install from the Google Play Store can download the apk from this repo's releases. Do note that OTA updates do not work if the app is installed through this method and the user has to manually update the app.</li>
