<h2>Getting started</h2>
<p>First you need an identity. Create one via the "Settings" menu, or import an existing identity. Afterwards, you can add your friends' addresses by copy-paste, or exchange them via QR Codes or NFC.</p>
<p>On Android lower than 4.4, it is recommended that you install <a href="market://details?id=org.openintents.filemanager">OI File Manager</a> for enhanced file selection. To share via QR Codes install <a href="market://details?id=com.google.zxing.client.android">Barcode Scanner</a>. Clicking on the links will open Google Play Store or F-Droid for installation.</p>
