 ## Usage
 
-You need to download and install [`signal-cli`], such that it is found in your `PATH`.
+This crate cannot be installed from crates.io directly. It depends on the
+official Rust implementation of [libsignal protocol], which is not published on
+crates.io.
 
-1. Download and install `signal-cli`
-2. Follow the instructions at
-   https://github.com/AsamK/signal-cli/wiki/Linking-other-devices-(Provisioning) to link
-   `signal-cli` to your phone/device.
-3. Install gurk with `cargo install gurk`
-4. Drop a config file with the following context
-    ```
-    [user]
-    name = "Your user name"
-    phone_number = "Your phone number used in Signal"
-    ```
+Either install the latest version via
 
-  in one of the following locations:
+```
+cargo install --git https://github.com/boxdot/gurk-rs gurk
+```
 
-1. `$XDG_CONFIG_HOME/gurk/gurk.toml`
-2. `$XDG_CONFIG_HOME/gurk.yml`
-3. `$HOME/.config/gurk/gurk.toml`
-4. `$HOME/.gurk.toml`
-
-  For more config options, see [`src/config.rs`].
-
-5. Run `gurk`
-
-At the first run, `gurk` will sync groups and contacts.
-
-## Missing features / known issues
-
-* Use a simple database (like sqlite, sled, leveldb) for storing messages, contacts, etc... instead
-  of a JSON file.
-* Add optional Gnome notifications over dbus.
-* Add scrolling of messages.
-* Add reply functionality to a single message.
-* Add mouse navigation.
-* Add search of messages/chats. Add quick switch between chats by name.
-* It is not possible to send multiline messages, since the `Enter` key sends the messages. Add a
-  shortcut or a mode for typing multiline messages.
-* Add sending of attachments.
-* Add support for blocked contacts/groups.
-
-The communication with the Signal backend is implemented via [`signal-cli`]. It provides some
-functionality like lookup of group/contact name only over the dbus interface. Therefore, `gurk` only
-works on Linux. We should evaluate if it is possible to switch to the [`libsignal-service-rs`]
-crate.
+or download a pre-compiled binary from [Releases].
