 # kube-ps1: Kubernetes prompt for bash and zsh
 
+![GitHub Release](https://img.shields.io/github/v/release/jonmosco/kube-ps1)
+[![CI](https://github.com/jonmosco/kube-ps1/actions/workflows/ci.yml/badge.svg)](https://github.com/jonmosco/kube-ps1/actions/workflows/ci.yml)
+

 configured on `kubectl` to your Bash/Zsh prompt strings (i.e. the `$PS1`).
 
 Inspired by several tools used to simplify usage of `kubectl`.
