chore: improve get started

[floridemai]

Getting started page was pretty empty and we choose to load the readme file and use that.

Options:

• "start" with the readme and create another example section as per the ticked
• simply add a how to use in the readme and just place the readme in the get started page
  (The tricky part is that it's a get started while the readme starts with a header and the name)

Solution:
I see what you mean, but considering the simplicity of the solution that embeds the readme, I'm happy with including the raw readme in there. Let's expand the readme with a simple usage section and we're done
