 ## BuildKit and Kubernetes
 
-BuildKit can be used as a build service in Kubernetes

+BuildKit can be used as a [build service in Kubernetes](https://github.com/moby/buildkit/tree/master/examples/kubernetes)
 
 ### Pod
 
-Proof-of-concept
-
 BuildKit understands the schema `kube-pod://`
 
 ### Deployment
 
-Multiple pods can run simultaneously
-
-Build is passed to any one of them by the service
+Load balancing works
 
 ### CLI
 
 `buildx` comes with options to deploy BuildKit based pods
