It would be beneficial to be familiar with the code for our service that we introduced in Chapter 4, Introduction to the ACME Registration Service .
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/ch06.
Instructions to obtain the code and configure the sample service are available in the README here 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, in ch06/acme.
