First, get a Kubernetes cluster, then:
1. Install stack
$ helm repo add presslabs https://presslabs.github.io/charts
$ helm install --namespace presslabs-sys presslabs presslabs/stack
2. Launch your site
$ kubectl apply -f ./my-awesome-site.yaml
Presslabs Stack can be installed on any major public cloud Kubernetes-enabled provider: AWS, Google Cloud, Azure, Digital Ocean or on any bare metal Kubernetes install.
