+**Note for Debian 7.x users**:
 To build packages on Debian 7 (Wheezy), you need to enable `debian-backports`
 to install systemd-compatibility packages like `dh-systemd` or `init-system-helpers`.
+Please follow the instructions on [Debian Backports](http://backports.debian.org).
 
 This also means that you can only install those built packages on systems that have
 `init-system-helpers` installed.
