+  shortDescription: Package manager for kubectl plugins.
+  caveats: |
+    krew is now installed! To start using kubectl plugins, you need to add
+    krew's installation directory to your PATH:
+
+      * macOS/Linux:
+        - Add the following to your ~/.bashrc or ~/.zshrc:
+            export PATH="${KREW_ROOT:-$HOME/.krew}/bin:$PATH"
+        - Restart your shell.
+
+      * Windows: Add %USERPROFILE%\.krew\bin to your PATH environment variable
+
+    To list krew commands and to get help, run:
+      $ kubectl krew
+    For a full list of available plugins, run:
+      $ kubectl krew search
+
+    You can find documentation at
+      https://krew.sigs.k8s.io/docs/user-guide/quickstart/.
