Before I wrote this chapter, I forked the vfarcic/go-demo-3 (https://github.com/vfarcic/go-demo-3) repository into vfarcic/go-demo-5 (https://github.com/vfarcic/go-demo-5). Even though most the code of the application is still the same, I thought it would be easier to apply and demonstrate the changes in a new repository instead of creating a new branch or doing some other workaround that would allow us to have both processes in the same repository. All in all, go-demo-5 is a copy of go-demo-3 on top of which I made some changes which we'll comment soon.
Since we'll need to change a few configuration files and push them back to the repository, you should fork vfarcic/go-demo-5 ...
