In this chapter, we looked at why having a plan is important when building big. We reviewed various design paradigms and key aspects of Golang. The discussion of these topics here was focused and very condensed. For more insights, I strongly recommend reading Clean Architecture: A Craftsman's Guide to Software Structure and Design by Robert C. Martin and A tour of Go (https://tour.golang.org/welcome/1).

In the next chapter, we will look at the problem statement of the case study that we will be working on for the rest of this book. At the end of each section of the book, we will apply whatever we learned in the section's chapters to build solutions for specific aspects of the case study.
