signal-cli was primarily developed to be used on servers to notify admins of important events.
For this use-case, it has a dbus interface, that can be used to send messages from any programming language that has dbus bindings.
+For some functionality the Signal protocol requires that all messages have been received from the server.
+The `receive` command should be regularly executed. In daemon mode messages are continuously received.
+
== Options
*-h*, *--help*::
*-v*, *--version*::
Print the version and quit.
+*--verbose*::
+Raise log level and include lib signal logs.
+
*--config* CONFIG::
Set the path, where to store the config.
Make sure you have full read/write access to the given directory.
Specify your phone number, that will be your identifier.
The phone number must include the country calling code, i.e. the number must start with a "+" sign.
+This flag must not be given for the `link` command.
+It is optional for the `daemon` command.
+For all other commands it is only optional if there is exactly one local user in the
+config directory.
+
*--dbus*::
Make request via user dbus.
*--dbus-system*::
Make request via system dbus.
+*-o* OUTPUT-MODE, *--output* OUTPUT-MODE::
+Specify if you want commands to output in either "plain-text" mode or in "json". Defaults to "plain-text"
+
== Commands
=== register
Use "updateAccount" to undo this.
To remove a linked device, use "removeDevice" from the master device.
+*--delete-account*::
+Delete account completely from server. Cannot be undone without loss. You will
+have to be readded to each group.
+
+CAUTION: Only delete your account if you won't use this number again!
+
=== updateAccount
Update the account attributes on the signal server.
=== link
Link to an existing device, instead of registering a new number.
-This shows a "tsdevice:/…" URI. If you want to connect to another signal-cli instance, you can just use this URI. If you want to link to an Android/iOS device, create a QR code with the URI (e.g. with qrencode) and scan that in the Signal app.

*-n* NAME, *--name* NAME::
Optionally specify a name to describe this new device.
Only works, if this is the master device.
*--uri* URI::
-Specify the uri contained in the QR code shown by the new device. You will need the full uri enclosed in quotation marks, such as "tsdevice:/?uuid=....."
+Specify the uri contained in the QR code shown by the new device.
+You will need the full uri enclosed in quotation marks, such as "tsdevice:/?uuid=....."
=== listDevices
Specify the device you want to remove.
Use listDevices to see the deviceIds.
+=== getUserStatus
+
+Uses a list of phone numbers to determine the statuses of those users.
+Shows if they are registered on the Signal Servers or not.
+In json mode this is outputted as a list of objects.
+
+[NUMBER [NUMBER ...]]::

Send a message to another user or group.
*-a* [ATTACHMENT [ATTACHMENT ...]], *--attachment* [ATTACHMENT [ATTACHMENT ...]]::

+
+*-t* TIMESTAMP, *--target-timestamp* TIMESTAMP::
+Specify the timestamp of the message to delete.
+
=== receive
Query the server for new messages.
-New messages are printed on standardoutput and attachments are downloaded to the config directory.
+New messages are printed on standard output and attachments are downloaded to the config directory.

+=== sendSyncRequest

+The master device will respond with synchronization messages with full contact and
+group lists.
+
=== uploadStickerPack
Upload a new sticker pack, consisting of a manifest file and the stickers in WebP format (maximum size for a sticker file is 100KiB).
=== daemon
signal-cli can run in daemon mode and provides an experimental dbus interface.
+If no `-u` username is given, all local users will be exported as separate dbus
+objects under the same bus name.
*--system*::
