 ## What it does
 
-`Deploy()` automatically creates a systemd unit file, reloads the systemd daemon
-so it can use it, enables the unit (so it starts on boot) and starts the service
+This package provides a simple interface to automatically creating and enabling a
+systemd "user unit" service, as part of your single-binary deployment.
+
+The `Deploy()` function creates the systemd unit file, reloads the systemd daemon
+so it reads it, enables the unit (to start on boot) and starts the service
 running.
 
-This means you can have a single binary deployment. Copy your executable to "somewhere"
-on your target system, run it with `-deploy` (or however you have enabled the call to `Deploy()`)
-and your application starts running in the background, and will restart on boot.

-There is also an `Undeploy()` func, which you should of course
-provide as an option to your users. It stops the running service, removes the unit file and restarts systemd.
