 # 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 receiving messages signal-cli uses a [patched libsignal-service-java](https://github.com/AsamK/libsignal-service-java), because libsignal-service-java [does not yet support registering for the websocket support](https://github.com/WhisperSystems/libsignal-service-java/pull/5) nor [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.

 It is primarily intended 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.
 
 ## Installation
