Why is this change needed?

It's needed because the readme has waaaaay to clutter, and is not clear and concise in giving the project info.

Additional Info

• Simplify the install process, having one section. This just makes it easier to install it.
• Deleate the api key reminder in usage notes, just have in the install process. Why 2? 1 is just fine.
• Has a little centered description at the start. This is to have a clear and concise explanation of what the software does.
• Move screenshots to the last parts. People don't want to see screenshots immodestly, they just want to see how to install it and use it.
• Beautification all-together. Explains it by itself.
