+	help
+	  Portable services are systemd services that can be dynamically
+	  attached and detached from the system.
+
+	  These services must come with their own root directory which
+	  they are bound to through an automatically generated drop-in.
+
+	  They also have restrictions applied by the host system in the
+	  form of profiles.
+
+	  This functionality is provided by the system service
+	  systemd-portabled along with the corresponding CLI
+	  portablectl.
