 Additionally you can supply a `'subtitle'` String option and a `'menu'` object option that will be passed to [terminal-menu](https://github.com/substack/terminal-menu) so you can change the `'bg'` and `'fg'` colours.
 
 The `'helpFile'` option is optional but if you supply one, users will get the contents of this file when they type `app help` (where 'app' is your workshop application name). They will also see a pointer to this whenever they select a new exercise, so make sure you fill it up with details of where to receive actual help for your workshop: a repo, a Google Group, an IRC channel, whatever.
 
+The `'setupsFile'` option is optional but if you supply one, users will get the contents of this file when they type `app setups` (where 'app' is your workshop application name). This file is intended to contain any instructions required for installations or setups which are prerequisites needed to begin the lessons.
