+# GitLab Pivotal Tile **[PREMIUM ONLY]**
+
+> Introduced in [GitLab Premium][eep] 8.2.
+
+Easily deploy GitLab as a pre-configured appliance using Ops Manager (BOSH) for
+[Pivotal Cloud Foundry][pcf].
+
+## Overview
+
+Enterprise admins want their development toolkit to be more customizable, more
+integrated, and more secure. With Pivotal Cloud Foundry, GitLab is installed and
+scales easily in a highly available environment.
+
+The upgrades are pain-free and well tested. All it takes is upload the new tile
+and click a button to begin the upgrade process.
+
+## Use cases
+
+- You want a highly available deployment with minimal effort. Scale horizontally
+  as your user base grows.
+
+## Features
+
+The GitLab Pivotal Tile is based on [GitLab Premium][eep] and includes nearly all of its features. The features in Premium but _not_ supported on the Tile are:
+
+* PostgreSQL
+* Pages
+* Geo
+* Registry
+* Mattermost
+* Subgroups
+* Elasticsearch
+* Service Desk
+* OAuth & Kerberos Authentication
