It's time for us to get to know the Ruby framework Hanami better.
Your task is to create a "Hello World" application in Hanami 2.0. Use the Hanami 2.0 tempalate and play along :)
The current stable version of Hanami is version 1.3, which the documentation covers. We are not interested in that version, but the next major version 2.0. They call it a "start fresh", which means more or less a total rewrite from scratch. Version 2.0 is heavily dependent on dry-rb as well as Ruby Object Mapper. Note that Hanami 2.0 is still under construction, so be careful to check the date of what you read. You can find the latest release notes here.
