  15
  16 == Description
  17
  18 signal-cli is a commandline interface for libsignal-service-java.
  19 It supports registering, verifying, sending and receiving messages.
  20 For registering you need a phone number where you can receive SMS or incoming calls.
  21 signal-cli was primarily developed to be used on servers to notify admins of important events.
  22 For this use-case, it has a dbus interface, that can be used to send messages from any programming language that has dbus bindings.
  23

 368
 369 == Files
 370
 371 The password and cryptographic keys are created when registering and stored in the current users home directory, the directory can be changed with *--config*:
 372
 373 `$XDG_DATA_HOME/signal-cli/` (`$HOME/.local/share/signal-cli/`)
 374
 375 For legacy users, the old config directories are used as a fallback:
 376
 377     $HOME/.config/signal/
 378
 379     $HOME/.config/textsecure/
