With the edits I made, looks good to me. But check my work too, y'all. 😅

A couple potential suggestions and questions! Nothing blocking.

Question: Does the rest of the proposals file structure make sense with this change? Should we create a core dir as well?

[amyleadem]

This is a good note. The repo was originally designed to just be for component proposals, and I think the recent repo growth is showing strangely in both the file structure and base README. Now that the repo will also include ADRs and Elements pre-alphas, we should at least address that in the README and consider if the file structure still makes sense. I've opened #19 to address the README piece of this.

Question: Not sure I follow what the the Web components variant is supposed to be listed as here.

Is this just the name of the variant? Would this differ from the USWDS 3 variant?

Thanks for creating this @amyleadem. Overall it looks good. Left a few comments, but nothing is blocking.

I've also made some formatting changes using the built-in markdown formatter in Prettier.

@amyleadem can you look into the formatting issue? We might have to move some code blocks out of comments.

Otherwise LGTM

@amyleadem can you look into display issues showing up in the preview?
