Not able to set it up for existing Ruby on Rails project

[tygrash]

This message is for the maintainers of this repo-

The Readme is so screwed up, that people are not able to setup sonarqube pipeline for Ruby on Rails project. It would have been much easier if you could elaborate the step-by-step integration of this plugin in a existing Rails project, because it is not at all possible to send any metrics to remote sonarqube server. I mean there should be a command which will run the sonarqube scanner and send metrics to a specific project_key on sonarqube server, but I can't find any such command for Rails in the documentation.
Also the indentation of README is very bad, that it took half hour to understand that we have to download this plugin and use somehow, which is not clear afterwards.

Hence a request to you guys to please update the Readme for a lame/beginner person, which is required in open source.
