+In Lab 1 you will pick your track and then throughout the labs look out for any special commands needed for the container orchestrator for your track.

-* Kubernetes track (click link below)
+The easiest and simplest way to learn about OpenFaaS is by deploying Docker Swarm, this is because it is already built into the Docker distribution and has more limited extensibility.
 
-You can also learn about OpenFaaS through Kubernetes. We have a preview available for learning OpenFaaS with Kubernetes. [Switch to the Kubernetes track](https://github.com/openfaas/workshop/tree/kubernetes-preview).
+The knowledge you build up and the functions you create are both transferrable and portable between Docker Swarm and Kubernetes.
+
+### Kubernetes (intermediate)
+
+You can also learn about Serverless on Kubernetes using OpenFaaS.
+
+The recommendation from the OpenFaaS community is that you run Kubernetes in production, but all the knowledge you can is transferrable and functions do not have to be rebuilt.

+You can create a remote cluster in the cloud and enjoy the same experience as if you were developing locally whilst saving on RAM/CPU and battery. The costs for running a cluster for 1-2 days is minimal.

+You can use free credits to create a cluster through DigitalOcean's UI.

+The DigitalOcean dashboard will then guide you through how to configure your `kubectl` and `KUBECONFIG` file for use in the labs.
