Hello and welcome to lesson number one. Lets see how we can install Sequence.js, and the first method is to go to their website which is sequence.js.com and go to Download. And here, you have the option of downloading the files manually or if you're using GitHub, if you're familiar with it you can a fork the GitHub repository. Or additionally you can use it via command line using NPM or Bower. Now, if you don't know how to use NPM or Bower, then I suggest you use these two methods. Either one of these two methods. But, if you do, then go ahead and use whatever package manager you want. In my case, I'll be using Bower. So, I'm gonna open up my terminal window here. I am using a code editor. That has a terminal built in but if you don't have one then simply open a terminal in your OS. And, once you navigate to your working folder you would say bower or npm install sequencejs, and that created the bower_components folder. That contains sequencejs along with some optional plugins, like hammerjs, images loaded and so on. Now, the files that you need can be found inside the scripts folder, sequence.js or sequence.min.js, I recommend you use .min.js. Now, if you downloaded sequence from either the website or from GitHub, you might find a slightly different folder structure, but the important files are the same, either sequence.js or sequence.min.js. And that's the end of this lesson. In the next one, I'll explain how to write the proper markup. See you there.
