This chapter was packed with all kinds of goodies. You should now understand the example application that we'll be building, the high-level game plan for the phases of our build, and the five-step process we're going to take for the first phase of our build.

We then moved on to what Sass is, and a few of its features that help us with creating our CSS for the application. We will study the tools to help you when you're writing the Sass for your applications. Next, we saw what Bootstrap is and how to integrate it into your applications. We studied what Bootstrap's grid is, and the basics for how to use it, along with some of Bootstrap's components and how to use them. 

Lastly, we studied the evolution of software projects, from inception to implementation. Here, we covered the different types of analysis, the gathering of the requirements and some use cases. We also covered wireframes, went into detail on the goal of each wireframe, and the basic design principles (that were mentioned during the description of the wireframes).

So far in the book, with the exception of the quick to-do app we've built in Chapter 1, Quick Start, we have not even touched Angular. This will change—starting with the next chapter, Chapter 4, Routing. In this chapter, we will create the Angular shell for our application using the CLI (as we did at the beginning of the book). However, we're going to be adding routing to it. I'll explain what routing is, and how to configure routing for our application as we work through it. 

So, before you turn the page, pat yourself on the back, stretch a little, and maybe pour yourself another glass of your favorite beverage. Well done, my fellow budding Angular gurus. With these first three chapters behind you, you are now ready to meet Angular!
