 ## General
 *K4wd* allows to make multiple resources in Kubernetes clusters available locally for development and debugging purposes in a pleasant way.
+It doesn't reinvent the wheel as it is basically a wrapper around [PortForwarder.ForwardPorts](https://pkg.go.dev/k8s.io/client-go/tools/portforward#PortForwarder.ForwardPorts) with some extras.
 While there are many similar tools available, *K4wd* might fill a niche. The primary goals are:
 - No need to install additional software in the clusters
 - No elevated privileges or additional software on the client
 - Declarative configuration for complex setups
 - Easy integration in development workflows
 
+## Use cases
+- Local development against upstream resources running in Kubernetes clusters
+- Comparison of workload bahaviours in different Kubernetes contexts
+
 ## Quickstart / Demo
 - Install *k4wd*: `go install github.com/tmsmr/k4wd/cmd/k4wd@latest`
 - Have some resources deployed: `kubectl apply -f docs/example.yaml`
