There are two ways to use Kel:
If you already have a Kubernetes cluster set up, you can just use Kel Layer 1, which provides components on top of Kubernetes that enable developers to define a workflow around managing the operations of their site.
If you don’t have a Kubernetes cluster, you can additionally use Kel Layer 0 which provides tooling around the setup of a cluster specifically for Kel (currently focused on the Google Cloud Platform but eventually multiple infrastructure providers).
