+# Kubernetes `kubectl` Helper Plugin
+
+Leverages a local `redis` application to quickly and easily set an alias `k` for `kubectl --context <some-context> --namespace <some-namespace>`.
+Much like scwrypts environments, `k` aliases are *only* shared amongst session with the same `SCWRYPTS_ENV` to prevent accidental cross-contamination.
+
+
+## Getting Started
+
+Enable the plugin in `~/.config/scwrypts/config.zsh` by adding `SCWRYPTS_PLUGIN_ENABLED__KUBECTL=1`.
+Use `k` as your new `kubectl` and checkout `k --help` and `k meta --help`.
