+== Description
+
+signal-cli is a commandline interface for libsignal-service-java.
+It supports registering, verifying, sending and receiving messages.
+For registering you need a phone number where you can receive SMS or incoming calls.
+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.

-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.

- uname -a | signal-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
+uname -a | signal-cli -u USERNAME send [RECIPIENT [RECIPIENT ...]]
Create a group::
- signal-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
+signal-cli -u USERNAME updateGroup -n "Group name" -m [MEMBER [MEMBER ...]]
Add member to a group::

Send a message to a group::
- signal-cli -u USERNAME send -m "This is a message" -g GROUP_ID
+signal-cli -u USERNAME send -m "This is a message" -g GROUP_ID
Trust new key, after having verified it::
- signal-cli -u USERNAME trust -v FINGER_PRINT NUMBER
+signal-cli -u USERNAME trust -v SAFETY_NUMBER NUMBER
Trust new key, without having verified it. Only use this if you don't care about security::
- signal-cli -u USERNAME trust -a NUMBER
-
-Files
------
-The password and cryptographic keys are created when registering and stored in the
-current users home directory, the directory can be changed with *--config*:
+signal-cli -u USERNAME trust -a NUMBER
-`$XDG_DATA_HOME/signal-cli/` (`$HOME/.local/share/signal-cli/`)
-
-For legacy users, the old config directories are used as a fallback:
+== Exit codes
+* *1*: Error is probably caused and fixable by the user
+* *2*: Some unexpected error
+* *3*: Server or IO error
+* *4*: Sending failed due to untrusted key
- $HOME/.config/signal/
+== Files
- $HOME/.config/textsecure/
