create a meaningful readme.md

[CapCalamity]

We really need some content for the Readme.md.
From other popular Repositories i have collected a list of things we should include in our Readme:

Example repositories

• oh-my-zsh
• github-changelog-generator

  List of things:

• short introduction
• index
• overview
  • features
  • future / planned features
• how to use program / how to set it up
• F.A.Q.
• advanced topics
  • maybe directing the user to the wiki
• how to contribute
• thanks / contributors
• license

Any suggestions? @SuNflOw1991

@SupremeVoid maybe we can use this as a basis, and expand upon it for the upcoming wiki from #37
