+
+To add new tags, see [`contrib/builder/rpm` in https://github.com/docker/docker](https://github.com/docker/docker/tree/master/contrib/builder/rpm), specifically the `generate.sh` script, whose usage is described in a comment at the top of the file.

+%description
+Docker is an open source project to pack, ship and run any application as a
+lightweight container
+
+Docker containers are both hardware-agnostic and platform-agnostic. This means
+they can run anywhere, from your laptop to the largest EC2 compute instance and
+everything in between - and they don't require you to use a particular
+language, framework or packaging system. That makes them great building blocks
+for deploying and scaling web apps, databases, and backend services without
+depending on a particular stack or provider.

-PACKAGE_DESCRIPTION="Linux container runtime
-Docker complements LXC with a high-level API which operates at the process
-level. It runs unix processes with strong guarantees of isolation and
-repeatability across servers.
-Docker is a great building block for automating distributed systems:
-large-scale web deployments, database clusters, continuous deployment systems,
-private PaaS, service-oriented architectures, etc."
