 Airship Seaworthy
 =================
 
-Airship Seaworthy is a multi-node Airship deployment reference, and pipeline.
+Airship Seaworthy is a multi-node site deployment reference
+and continuous integration pipeline.
 
 The site manifests are available at
 `site/airship-seaworthy <https://github.com/openstack/airship-treasuremap/tree/master/site/airship-seaworthy>`__.
 
+
+Pipeline
+--------
+
+Airship Seaworthy pipeline automates deployment flow documented in
+`Site Authoring and Deployment Guide <https://airship-treasuremap.readthedocs.io/en/latest/authoring_and_deployment.html>`__.
+
+The pipeline is implemented as Jenkins Pipeline (Groovy), see code for the pipeline at
+`Jenkinsfile <https://github.com/openstack/airship-treasuremap/blob/master/tools/gate/Jenkinsfile>`__.
+
+Versions
+--------
+
+The manifest overrides (`versions.yaml <https://github.com/openstack/airship-treasuremap/blob/master/global/software/config/versions.yaml>`__)
+are setup to deploy OpenStack Ocata.
+
+The versions are kept up to date via `updater.py <https://github.com/openstack/airship-treasuremap/blob/master/tools/updater.py>`__,
+a utility that updates versions.yaml latest charts and (selected) images.
+
+The pipeline attempts to uplift and deploy latest versions on daily bases.
+
+
+Hardware
+--------
+
+The site has 6 DELL R720xd bare-metal servers, 4 control and 2 compute nodes.
+See host profiles for the servers `here <https://github.com/openstack/airship-treasuremap/tree/master/site/airship-seaworthy/profiles/host>`__.
+
+Control (masters)
+ - cab23-r720-11
+ - cab23-r720-12
+ - cab23-r720-13
+ - cab23-r720-14
+
+Compute (workers)

+
+Network
+-------
+
+Physical (underlay) networks are described in Drydock site configuration
+`here <https://github.com/openstack/airship-treasuremap/blob/master/site/airship-seaworthy/networks/physical/networks.yaml>`__.
+It defines OOB (iLO/IPMI), untagged PXE, and multiple tagged general use networks.
+
+Calico overlay for k8s POD networking uses IPIP mesh.
+
+BGP peering is supported but not enabled in this setup, see
+`Calico chart <https://github.com/openstack/openstack-helm-infra/blob/master/calico>`__.
