 This book will teach you the basics of setting up your developer environment on a new MacBook. I have tried these on Mountain Lion and Mavericks but they might be more inclined towards Mavericks. Whether you are an experienced programmer or not, this book is intended for everyone to use as a reference when installing some language/library.

 We will set up [Node](http://nodejs.org/) (JavaScript), [Python](http://www.python.org/), [CPlusPlus](http://www.cplusplus.com/), and [Ruby](http://www.ruby-lang.org/) environments, mainly for JavaScript and Python development. Even if you don't program in all three, it is good to have them as many command-line tools use one of them. We also install a few daily use application and Latex. As you read and follow these steps, feel free to send me any feedback or comments you may have.
