 ## Overview
 
 This charm deploys and configures a node with OpenStack Ironic which has 
-integration with other OpenStack components. Services from the node are: 
-`ironic-api`, `ironic-conductor`, `tftpd-hpa` and optionally `nginx`.
-
-Nginx is optionally used as a light-weight web server used to serve
-iPXE files over http, in case the charm is configured to use iPXE instead of
-traditional PXE.

 OpenStack Ironic supports integration with Neutron, which is used as a DHCP
 provider for the `ironic-conductor.`
 
-As a requirement, prior to deploying the charm, you'll have to configure the
-`neutron-gateway` node with a flat network provider that uses a NIC which is
-connected to an isolated network dedicated for Ironic traffic.
-
-When iPXE is enabled, DHCP requests from iPXE need to have a DHCP tag called
-"ipxe", in order for the DHCP server to tell the client to get the "boot.ipxe"
-script via HTTP. Thus, you must configure `neutron-gateway` units accordingly:
-
-    juju set neutron-gateway dnsmasq-flags="dhcp-userclass=set:ipxe,iPXE, dhcp-match=set:ipxe,175"
