How to get OpenStack
OpenStack is a large and fast moving project. We are also an upstream project, with a large community of packagers and distributions who redistribute our work.
The best way to install OpenStack is to rely on one of the downstream distributions, which will take care of many of the details for you. There are also source code installers oriented towards developers.
Also, you don't have to install OpenStack - there are Cloud services that can provide OpenStack, without ever installing the software.
The current release of OpenStack is 2013.2 Havana

- RDO, at openstack.redhat.com, is a packaging of OpenStack for Red Hat distributions (Fedora, RHEL, CentOS, SL) using Packstack, which uses Puppet.
For developers, there are installers that create a core development environment.
