-Summary:Messenger for secured chats and groups
+Summary:Messenger for secured chats and groups (end-to-end encrypted)
 Description:
-Messenger that works via e-mail server. It is based on IMAP and QuickMSG, and
-therefore does not depend on an overall centralized server.
+Messenger that works via e-mail server, end-to-end encrypted.
+
+Text messages are not only end-to-end encrypted, they also get stored on your
+device in an encrypted way. Images, attachments etc. can be sent (encrypted, of
+course, but since they depend on third-party programs, they are stored
+unencrypted). Dib2Qm (aka Dibdib Messenger) makes use of your device's
+'Download' folder.
+
+It is possible to use the address of your device's 'Google account', but they
+insist on you explicitly allowing messenger apps: you would log in with your
+browser (!), go to 'Settings', 'Forwarding...IMAP', 'Enable IMAP', 'Save', then
+to 'Accounts', 'Other ... settings', '...Security', '2-Step...', 'Off', and
+'Connected apps', 'Allow less secure', 'On'.
+
+Strange? It is easier to use an extra e-mail account for Dib2Qm, but depending
+on your provider you might still have to allow IMAP services. Both, using the
+account's address and using a dedicated e-mail address for Dib2Qm, have their
+advantages and disadvantages ...
+
+Just try it out! -- on a non-critical device (And if your e-mail provider blocks
+it, use a different provider.)
+
+If you want to do a complete re-start, go to the device's settings, clear the
+app data, then open a file manager, clear the 'Download/dibdib' data, and then
+you can start the app a-fresh.
