+      The package creates a ``_buildslave`` system user, installs an
+      ``rc.d`` service, and creates ``/var/buildslave/`` as the default
+      worker directory.
+
+      Create the worker (replace ``WORKERNAME`` and ``WORKERPASSWD`` with
+      the credentials provided to you from your buildmaster-config issue)::
+
+         su -m _buildslave -c "buildbot-worker create-worker \

+             buildbot-api.python.org:9020 WORKERNAME WORKERPASSWD"
+
+      Edit ``info/admin``, ``info/host``, and ``buildbot.tac`` in the worker
+      directory (see below for recommended settings).
+
+      Enable and start the service::
+
+         rcctl enable buildbot_worker
+         rcctl start buildbot_worker
+
+      The ``rc.d`` script supports a single worker.  To run multiple
+      workers, create each in a subdirectory and point the service flags
+      at the desired one (or create additional ``rc.d`` scripts)::
+
+         su -m _buildslave -c "buildbot-worker create-worker \

       or use the cronjob approach described in the Linux tab.
