Documentation lacks Getting Started

[crazyjurich]

As a new user of k9s I wanted to try it out, I installed and ran it easily. But then I was stuck - what to do next? I use kubectl, my clusters are under .kube/, but k9s did not pick them up automatically, documentation doesn't say how to add new clusters, it just says where the cluster configuration resides, but that config doesn't have anything like IP and secrets.
Please add some info to documentation regarding cluster management and/or Getting Started
