-Applying a configuration to a node will cause `pocketknife` to check whether `chef` is installed. It it's not present, it will prompt you for whether you'd like to have it automatically installed. You can run `pocketknife -i` to always install chef without prompting if its needed, or run `pocketknife -I` to never install chef automatically if its needed and just quit.
+When deploying a configuration to a node, `pocketknife` will check whether Chef and its dependencies are installed. It something is missing, it will prompt you for whether you'd like to have it install them automatically.

+To always install Chef and its dependencies when they're needed, without prompts, use the `-i` option, e.g. `pocketknife -i henrietta`. Or to never install Chef and its dependencies, use the `-I` option, which will cause the program to quit with an error rather than prompting if Chef or its dependencies aren't installed.
