Package using cargo-deb

Using cargo-deb now produces a reasonably decent package.  It installs
command line completions, the binaries, udev rules, D-Bus
configuration and the systemd system service, leaving the service started.

+A D-Bus daemon and tool to control the screen backlight.  The daemon
+can also directly listen for ACPI events from acpid while the tool can
+also work without the daemon, though may need a little more setup for
+permissions.  The daemon will also detect changes made outside of it's
+control and publish the relevant D-Bus events, ensuring it integrates
+seamlessly with other tooling.
+
+By default a systemd system service is installed and enabled, running
+the daemon with acpi support.  It is also possible to run the daemon
+in a user-session and using the Session D-Bus.

 Installing
 ==========
 
+Using cargo-deb
+---------------
+
+If you are using a Debian-based distribution the easiest is to use
+`cargo-deb` to create and install a Debian package:
+
+```
+$ cargo install cargo-deb
+$ cargo deb --install
+```
+
+This will install the binaries, D-Bus configuration, udev-rules and
+systemd service unit.  The systemd service will be started with ACPI
+support.  After installation your brightness buttons should "just
+work" and you should be able to use `brightctl` to control the
+brightness as well, thanks to the udev rules even when stopping the
+`brightd` daemon.
+
+Read on for more details about all the parts involved.
+
+
+Manual Installation
+-------------------

 To use the ``brightctl`` tool without daemon support simply install
 the tool in any bin directory of your choice which is on your path.

 Since we'll start the service using D-Bus bus-activation this is all
 which needs to be done for systemd.
