openrc-init.c and openrc-shutdown.c are based on code which was written by
James Hammons <jlhamm@acm.org>, so I would like to publically
thank him for his work.

+.Sh NAME
+.Nm openrc-init
+.Nd the parent of all processes
+.Sh SYNOPSIS
+.Nm
+.Sh DESCRIPTION
+.Nm
+is an init process which can be an alternative to sysvinit or any other
+init process.
+.Pp
+To use
+.Nm
+configure your boot loader to invoke it or symlink it to /sbin/init.
+Also, you will need to use
+.Xr openrc-shutdown 8 ,
+to halt, reboot or poweroff the system.
+.Pp
+The default runlevel is read from the init command line, the
+rc_default_runlevel setting in rc.conf, the kernel command line, or it is
+assumed to be "default" if it is not set in any of these places.
+.Pp
+.Nm
+doesn't manage getty's directly, so you will need to manage them another
+way. For example, you can use the agetty service script as described in
+agetty-guide.md in this distribution.
+.Sh BUGS
+OpenRC 0.25 contains the first release of this init process.
+I do not know of any specific issues. However, if you use it, please be
+aware that there may be bugs and report any issues you find.
