Looks great! Looking towards @ali-khosh for a second look as well

Please use "ExecuTorch" vs. "Executorch" when referring to the project for consistency.

In this particular instance please replace Executorch with Edge and point it to https://pytorch.org/edge to make it consistent with the headers on other pages.

Before we land this, is there a sign off(in form of a review for example) from someone that we are removing the mobile section?

https://docs.google.com/document/d/1slnDApwhccfKI2qf75eOtA4ilyMCGF1tM36GxMBOR4U/edit#heading=h.xys1j0me4mye says to replace mobile with executorch, do you want to replace mobile with edge instead? Is there some other reference to mobile that I'm not seeing?

I'm guessing @ali-khosh would be the authority here

@seemethere yes please go ahead. OK to remove the PT Mobile link
