+# kubectx - show active kubectl context
+
+This plugins adds ```kubectx_prompt_info()``` function. It shows name of the
+active kubectl context (```kubectl config current-context```).
+
+You can use it to customize prompt and know if You are on prod cluster ;)
+
+_Example_. Add to **.zshrc**:
+
+```
+RPS1='$(kubectx_prompt_info)'
+```
+
+### custom ctx names
+
+One can rename default context name for better readability.
+
+_Example_. Add to **.zshrc**:
+```
+kubectx_mapping[minikube] = "mini"
+kubectx_mapping[context_name_from_kubeconfig]="$emoji[wolf_face]"
+kubectx_mapping[production_cluster]="%{$fg[yellow]%}prod!%{$reset_color%}"
+```
