+\subsection{Directions}
+
+Scan this QR code to quickly import the wallet backup file into a digital
+device. \\
+\\
+The data file can be used by Caravan software, a stateless multisig coordinator: \\
+\texttt{https://unchained-capital.github.io/caravan/} \\
+\\
+The data contained within the wallet backup file can also be entered into
+other wallet software, such as Electrum, Sparrow and Specter.
