Deis is an open source PaaS that makes it easy to deploy, scale and manage containers used to host applications and services. Deis builds on Docker and CoreOS to provide a private PaaS that is lightweight and flexible.
If you are new to Deis, start with :ref:`Concepts` and basic :ref:`Usage` of the command-line client. Follow the :ref:`Developer Guide <developer>` to deploy an application on Deis. The :ref:`Operations Guide <operations>` will guide you through deploying Deis itself.
Want to learn about Deis internals? You'll find complete API documentation in the :ref:`client` and :ref:`server` sections.
