+# Quick Start for GCE
+
+1. Create a VM:
+
+```bash
+$ gcloud compute instances create --machine-type e2-standard-8 --boot-disk-size 60GB nephio-r1-e2e
+```
+
+2. SSH to the VM:
+
+Googlers (you also need to run `gcert`):
+```bash
+$ gcloud compute ssh nephio-r1-e2e -- -o ProxyCommand='corp-ssh-helper %h %p' -L 7007:localhost:7007
+```
+
+Everyone else:
+```bash
+$ gcloud compute ssh nephio-r1-e2e -- -L 7007:localhost:7007
+```
+
+3. On the machine, run this:
+
+```bash
+$ sudo apt-get install -y git
+$ git clone https://github.com/nephio-project/test-infra.git
+$ sed -e "s/vagrant/$USER/" < test-infra/e2e/provision/nephio.yaml > ~/nephio.yaml
+$ cd test-infra/e2e/provision/
+$ ./gce_run.sh
+$ kubectl --kubeconfig ~/.kube/mgmt-config port-forward --namespace=nephio-webui svc/nephio-webui 7007
+```
+
+You can now navigate to
+[http://localhost:7007/config-as-data](http://localhost:7007/config-as-data) to
+browse the UI.
+
+You probably want a second ssh window open to run `kubectl` commands, etc.,
+without the port forwarding (which would fail if you try to open a second ssh
+connection with that setting).
+
