-### MongoDB Enterprise Database
\ No newline at end of file
+# MongoDB Enterprise Database #
+
+MongoDB is a general purpose, distributed document database designed for ease of development and scaling.  Its key features include a flexible JSON-like document data model, high performance, a rich query language, high availability, and horizontal scalability.
+
+This MongoDB Enterprise Database image is used by the MongoDB Enterprise Kubernetes Operator, and in conjunction with MongoDB Ops Manager, to provision and manage MongoDB database deployments (replica sets, sharded clusters, and standalone MongoDB instances) through Kubernetes and OpenShift.  It contains an Automation Agent that connects to management services provided by Ops Manager. Together, the Enterprise Operator and Ops Manager provide a management and orchestration layer to run MongoDB Enterprise within Kubernetes and OpenShift clusters.  Ops Manager can itself be deployed to the cluster or stood up separately.  
+
+For more information about MongoDB, please visit <https://www.mongodb.com>.
+
+More information about MongoDB Ops Manager can be found at <https://www.mongodb.com/products/ops-manager>.
+
+## Documentation ##
+
+Documentation for the MongoDB Enterprise Kubernetes Operator is available at <https://docs.mongodb.com/kubernetes-operator>.
