+Process management
+==================
+
+There following should be taken into consideration when running without systemd:
+
+* To utilize multiple CPUs, kresd has to be executed as several independent
+  processes.
+* Maintenance daemon(s) have to be executed separately.
+* If a process crashes, it might be useful to restart it.
+* Using some mechanism similar to :ref:`mod-watchdog` might be desirable to
+  recover in case a process becomes unresponsive.
+
+Please note, systemd isn't the only process manager and other solutions exist,
+such as supervisord_. Configuring these is out of the scope of this
+document. Please refer to their respective documentations.
+
+It is also possible to use kresd without any process management at all, which
+may be suitable for some purposes (such as low-traffic local / home network resolver,
+testing, development or debugging).
