Complete and rework the developer guide in the Readme

[Askir]

Story:

As a new Developer getting started I want to see a guide instructing the use of this tool In order to understand the basics of this tool and how it works

Description:

Currently the guide is not very complete and doesn't actually work. The step definitions at the bottom are incomplete. Some setences have typos and bad wording.

Acceptance Criteria:

• [ ] All stepdefinitions in the steps section so you can copy and paste
• [ ] Working acceptance test once you've completed all steps (They should not throw exceptions etc.)
• [ ] Better wording, no typos

The library methods should be in seperate blocks.

The fact that the libraries method needs to be class side should be fat!

no spaces in stepnames in readme so it doesn't crash.

assert should be change to self assert
