In this chapter, we started by looking at the fundamental setup for running Go projects successfully. Then we looked at how to install dependencies for our Go projects and how to structure our project. We also looked at the important concepts behind Containers, what problems they solve, and how we will be using them in the book along with an example. Next, we looked at how to write tests in Go, and along the way, we learned a few interesting concepts when dealing with a variadic function and other useful test functions.

In the next chapter, we will start looking at one of the core fundamentals of Go programming—goroutines and the important details to keep in mind when using them.
