+===========================
+Enabling Bilean in DevStack
+===========================
+
+1. Download DevStack:
+     git clone https://git.openstack.org/openstack-dev/devstack
+     cd devstack
+
+2. Add this repo as an external repository::
+
+     cat > /opt/stack/devstack/local.conf << END
+     [[local|localrc]]
+     enable_plugin bilean https://github.com/openstack/bilean master
+     END
+
+3. Add Plugin Configuration Hooks
+
+Bilean service is driven using a plugin mechanism for integrating to other
+services. Each integrated service may require additional configuration
+settings. For example, typically, you will need to add the
+``billing_notifications`` notification topic to each service's configuration.
+
+4. Then run devstack normally::
+
+    cd /opt/stack/devstack
+    ./stack.sh
