Vary is not as useful as it could be, and Key paired with Client Hints is starting to change that. Follow along with browser support to find out when you can start using them. And much more!

In this article, Myriam Jessier outlines how to get started with AMP and how to gain an edge over the competition with your e-commerce website.
