 ## systemd Service Notification
 
-The `daemon` package is an implementation of the [sd_notify protocol](https://www.freedesktop.org/software/systemd/man/sd_notify.html#Description). It can be used to inform systemd of service start-up completion, watchdog events, and other status changes.

 ## D-Bus
 
-The `dbus` package connects to the [systemd D-Bus API](http://www.freedesktop.org/wiki/Software/systemd/dbus/) and lets you start, stop and introspect systemd units. The API docs are here:
