+# Using runit with OpenRC
+
+Beginning with OpenRC-0.21, we support using runit [1] in place of
+start-stop-daemon for monitoring and restarting daemons.
+
+## Setup
+
+Documenting runit in detail is beyond the scope of this guide. It will
+document how to set up OpenRC services to communicate with runit.
+
+### Use Default start, stop and status functions
+
+If you write your own start, stop and status functions in your service
+script, none of this will work. You must allow OpenRC to use the default
+functions.
+
+### Dependencies
+
+All OpenRC service scripts that want their daemons monitored by runit
+should have the following line added to their dependencies to make sure
+the runit scan directory is being monitored.
+
+need runsvdir
+
+### Variable Settings
+
+The most important setting is the supervisor variable. At the top of
+your service script, you should set this variable as follows:
+
+supervisor=runit
+
+The second variable you need is runit_service. This is the path to the
+runit service you wish to control via OpenRC. The default is
+/etc/sv/${RC_SVCNAME}. This means that for an OpenRC service
+/etc/init.d/foo, you will need to create the same runit service in
+/etc/sv/foo.
+
+This is very early support, so feel free to file bugs if you have
+issues.
