+You can join either by opening these links in the app or by opening them in a desktop browser and scanning the QR code.
+
+## Make a private connection
+
+You need to share a link with your friend or scan a QR code from their phone, in person or during a video call, to make a connection and start messaging.
+
+The channel through which you share the link does not have to be secure - it is enough that you can confirm who sent you the message and that your SimpleX connection is established.
