+# kubectls - one command to rule your all kubectl contexts
+
+Are you operating in multi-cluster environment? Are you tired of constantly switching your kubectl contexts to execute the same command in different clusters?
+Good news! `kubectls` is here to help you!
+
+`kubectl` takes one kubernetes context as an input and executes the command in this context.
+`kubectls` takes **a list of kubernetes context separated by comma** and simply executes the same command in each context!
+
+... and it's less than 70 lines of code!
+
+
