Creating my GO RESTful API

To contribute to my Back-End studies, I decided to develop two APIs in different technologies. In the future I intend to use both APIs developed in a personal project related to games. For now both are being done in the REST architecture, because it is the most common, it is easier to work with, later one of the architectures will change to RPC.
