-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).
+signal-cli is a commandline interface for the [Signal messenger](https://signal.org/).

 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 daemon mode with D-BUS
+interface ([man page](https://github.com/AsamK/signal-cli/blob/master/man/signal-cli-dbus.5.adoc)) and JSON-RPC interface ([documentation](https://github.com/AsamK/signal-cli/wiki/JSON-RPC-service)).
+For the JSON-RPC interface there's also a simple [example client](https://github.com/AsamK/signal-cli/tree/master/client), written in Rust.

 ## 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/) and there is a [FreeBSD port](https://www.freshports.org/net-im/signal-cli) available as well. You need to have at least JRE 11 installed, to run signal-cli.

+
+System requirements:
+
+- at least Java Runtime Environment (JRE) 17
+- native library: libsignal-client
+
+  The native libs are bundled for x86_64 Linux (with recent enough glibc), Windows and MacOS. For other
+  systems/architectures
+  see: [Provide native lib for libsignal](https://github.com/AsamK/signal-cli/wiki/Provide-native-lib-for-libsignal)

+command). This is required for the encryption to work efficiently and for getting updates to groups, expiration timer
+and other features.

-If you use a version of the Oracle JRE and get an InvalidKeyException you need to enable unlimited strength crypto. See https://stackoverflow.com/questions/6481627/java-security-illegal-key-size-or-default-parameters for instructions.
