 ## Pre-requisite (Linux/MacOS)
 
+Please use the dev container configuration in the `.devcontainer` folder with [devpod](devpod.sh) or any other dev container environment to create minikube cluster with all the required pre-requisites such as helm, kubectl and flux for local testing. You can skip over to the local testing section if you use dev container environment.
+
 This solution requires Flux CLI locally and Flux Controller on your Kubernetes cluster. Flux requires access to a source repository via api and access to the kubernetes cluster you want to use for testing. Please follow the below steps for installing these pre-requisites.
 
 If you do not already have access to a running kubernetes cluster you can consider setting up an [EKS Anywhere local cluster](https://anywhere.eks.amazonaws.com/docs/getting-started/local-environment/) on docker provider or a local [k3s](https://k3s.io/) cluster or you may choose a hosted service such as [AWS EKS](https://aws.amazon.com/eks/).
