You can either build a release from sources or download a pre-built release. If you don't plan on developing Kubernetes itself, we suggest a pre-built release.
The list of binary releases is available for download from the [GitHub Kubernetes repo release page](https://github.com/GoogleCloudPlatform/kubernetes/releases).
Download the latest release and unpack this tar file on Linux or OS X, cd to the created `kubernetes/` directory, and then follow the getting started guide for your cloud.
Get the Kubernetes source. If you are simply building a release from source there is no need to set up a full golang environment as all building happens in a Docker container.
