What you need for this book

To get started using Bootstrap 4 there are a few tools I would recommend installing on your computer. First of all you'll need a text editor like Sublime Text or Notepad. Secondly you'll need a command line tool. If you're on a MAC you can use Terminal which is included with OSX. If you're on Windows I would recommend downloading Cygwin. That's all you need to get started with the book. In Chapter 2, Using Bootstrap Build Tools, I'll cover the installation of a few other tools that we'll be using in our project like: Node.js, NPM, Grunt.js, Jekyll, Harp.js and Sass. If you already have those tools installed great! If not, don't worry we'll go through it step by step later in the book.
