+
+If you want to build Kubernetes right away there are two options:
+
+* You have a working [Go environment](https://golang.org/doc/install).
+
+```
+$ go get -d k8s.io/kubernetes
+$ cd $GOPATH/src/k8s.io/kubernetes
+$ make
+```
+
+* You have a working [Docker environment](https://docs.docker.com/engine/).
+
+```
+$ git clone https://github.com/kubernetes/kubernetes
+$ cd kubernetes
+$ make quick-release
+```
+
+If you are less impatient, head over to the [developer's documentation](https://github.com/kubernetes/community/tree/master/contributors/devel).
