I’ve created a new Connecting Grbl Wiki Page in this repo that is specific to the Mega. I had some trouble finding this information, so I thought making it a page would be helpful. The information came from this issue and I’ve copied just the first bit of the Connecting Grbl page from the main Wiki.
I filed this issue to let the maintainers know of the new page. If you find it not satisfactory please feel free to remove it.
