-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). 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
+
+You can [build signal-cli](#building) yourself, or use the [provided binary files](https://github.com/AsamK/signal-cli/releases/latest), which should work on Linux, macOS and Windows. For Arch Linux there is also a [package in AUR](https://aur.archlinux.org/packages/signal-cli/). You need to have at least JRE 7 installed, to run signal-cli.
+
+### Install system-wide on Linux
+See [latest version](https://github.com/AsamK/signal-cli/releases).
+```sh
+export VERSION=<latest version, format "x.y.z">
+wget https://github.com/AsamK/signal-cli/releases/download/v"${VERSION}"/signal-cli-"${VERSION}".tar.gz
+sudo tar xf signal-cli-"${VERSION}".tar.gz -C /opt
+sudo ln -sf /opt/signal-cli-"${VERSION}"/bin/signal-cli /usr/local/bin/

+The USERNAME (your phone number) must include the country calling code, i.e. the number must start with a "+" sign. (See [Wikipedia](https://en.wikipedia.org/wiki/List_of_country_calling_codes) for a list of all country codes.
