It would be beneficial to be familiar with the code for our service, as introduced in Chapter 4, Introduction to ACME registration service. This chapter also assumes that you have read Chapter 5, Dependency Injection with Monkey Patching, through to Chapter 10, Off-the-Shelf Injection, on the various DI methods and other various improvements we made along the way.

You might also find it useful to read and run the full versions of the code for this chapter, which are available at https://github.com/PacktPublishing/Hands-On-Dependency-Injection-in-Go/tree/master/ch12.

Instructions for obtaining the code and configuring the sample service are available in the README, which can be found at https://github.com/PacktPublishing/Hands-On-Dependency-Injection-in-Go/.

You can find the code for our service, with the changes from this chapter already applied, at https://github.com/PacktPublishing/Hands-On-Dependency-Injection-in-Go/tree/master/ch12/acme.
