 ## Setup
 
-All you'll need to follow along with this book is Framer Studio or Framer.js and CoffeeScript. For the earlier chapters, I recommend typing code into a browser-based console to observe the output yourself. I suggest [CoffeeScript REPL](http://larryng.github.io/coffeescript-repl/), or if you're familliar with Chrome's web developer console, you can add a plugin that will let you run CoffeeScript, like [CoffeeConsole](http://snook.ca/archives/browsers/coffeeconsole) or [Scratch JS](https://chrome.google.com/webstore/detail/scratch-js/alploljligeomonipppgaahpkenfnfkn) (go to settings and select "CoffeeScript" for the transformer).

 **Note**: if you're in a browser environment, anywhere you see the command `print`, substitute `console.log`. `print` is unique to Framer Studio.

 ### Mapping values to arrays
 
-Right now, our cards are all the same colour (slightly transparent blue), they just look like different shades because they're stacked on top of each other. If we wanted to make them different colors, we can store a bunch of colors in an array, and then use those colors for the background colors of the cards.

 # Getting help
 
-First of all, if you work with developers, they should be the first people you ask for help. You'll find that a lot of developers love sharing their knowledge and are generally excited when other members of their team take an interest in code. It doesn't matter if your coworkers have never seen CoffeeScript before; the concepts are similar accross all programming languages and they'll probably be able to help anyways.
