+## Wrappers
+
+This plugin provides 3 wrappers to colorize kubectl output in JSON and YAML using various tools (which must be installed):
+
+- `kj`: JSON, colorized with [`jq`](https://stedolan.github.io/jq/).
+- `kjx`: JSON, colorized with [`fx`](https://github.com/antonmedv/fx).
+- `ky`: YAML, colorized with [`yh`](https://github.com/andreazorzetto/yh).
