AMP HTML is a way to build web pages that render with reliable and fast performance. It is our attempt at fixing what many perceive as painfully slow page load times – especially when reading content on the mobile web. AMP HTML is built on existing web technologies; an AMP page will load (quickly) in any modern browser.
You can learn more at ampproject.org including what AMP is, how it works and the importance of validation in AMP. You can also walk through creating an AMP page and read through the reference docs.
