Broken links in readme.md

[ShashankaNataraj]

The “white labelling” link redirects to a broken storybook page

Edit: this one is broken as well: CSS Variables for non-React Projects

Same with RFCsas well. This one points to a file in a deleted branch.

Thanks for pointing out. We'll keep it open for anyone who wants to take it
