 MetalLB hooks into your Kubernetes cluster, and provides a network load-balancer implementation. In short, it allows you to create Kubernetes services of type “LoadBalancer” in clusters that don’t run on a cloud provider, and thus cannot simply hook into paid products to provide load-balancers.
 ```
-This playbook aims to automate [this](https://metallb.universe.tf/tutorial/layer2/tutorial). It deploys MetalLB into kubernetes and sets up a layer 2 loadbalancer.
