 # signal-cli
 
 signal-cli is a commandline interface for [libsignal-service-java](https://github.com/WhisperSystems/libsignal-service-java). It supports registering, verifying, sending and receiving messages.
-To be able to link to an existing Signal-Android/signal-cli instance, signal-cli uses a [patched libsignal-service-java](https://github.com/AsamK/libsignal-service-java), because libsignal-service-java does not yet support [provisioning as a slave device](https://github.com/WhisperSystems/libsignal-service-java/pull/21).

 For registering you need a phone number where you can receive SMS or incoming calls.
 signal-cli is primarily intended to be used on servers to notify admins of important events. For this use-case, it has a dbus interface ([man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli-dbus.5.adoc)), that can be used to send messages from any programming language that has dbus bindings.

   You can register Signal using a land line number. In this case you can skip SMS verification process and jump directly to the voice call verification by adding the `--voice` switch at the end of above register command.

+**Hint**: The Signal protocol expects that incoming messages are regularly received (using `daemon` or `receive` command).
+This is required for the encryption to work efficiently and for getting updates to groups, expiration timer and other features.
 
 ## Storage
 
 The password and cryptographic keys are created when registering and stored in the current users home directory:
 
-`$XDG_DATA_HOME/signal-cli/data/` (`$HOME/.local/share/signal-cli/data/`)
-
-For legacy users, the old config directories are used as a fallback:
-
-        $HOME/.config/signal/data/

-        $HOME/.config/textsecure/data/
