+## runit-openrc-wrapper
+
+A small wrapper for runit based systems (e.g. __Voidlinux__) to use a subset of
+openrc's `rc-service` and `rc-update` commands.
+
+## Motivation
+
+I wanted to use __Ansible__ for my __Voidlinux__ systems and patching
+__Ansible__'s "`service`" module seems to be a PITA. So I decided to write a
+small wrapper which is detected by __Ansible__ as openrc. Attention!
+"`ansible_service_mgr`" variable of "`setup`" module still contains "`runit`"!
+
+## Installation
+
+Just copy all `rc-*` files to `/usr/bin` or another location in your root's
+PATH.
