Building a Vapor application from scratch

Before we start creating Vapor applications using the Vapor toolbox, which is an awesome tool provided by the Vapor team, let's see the minimal amount of code needed to create a Vapor application from scratch using the Vapor package. To do so, we need to follow the following steps:
