Code looks great--super clean integration!

Visually I'd like to get the "social proof" higher up on the page, so I'd prefer to swap it vertically with "used by".

Looking at https://www.styled-components.com/ as a reference.

@SachaG any thoughts on a visual cleanup here, now that we are getting more stuff on the homepage?

Sounds pretty easy to do what you want @shilman But would you mind doing it?

I have the feeling you know how you want it, and I don't want this to take too long.

Not being able to search on documentation sites drives me mad 😜

We will redesign later
