Description

This plugin adds support for the Accelerated Mobile Pages (AMP) Project, which is an open source initiative that aims to provide mobile optimized content that can load instantly everywhere.

With the plugin active, all posts on your site will have dynamically generated AMP-compatible versions, accessible by appending /amp/ to the end your post URLs. For example, if your post URL is http://example.com/2016/01/01/amp-on/, you can access the AMP version at http://example.com/2016/01/01/amp-on/amp/. If you do not have pretty permalinks enabled, you can do the same thing by appending ?amp=1, i.e. http://example.com/?p=123&amp=1

Note #1: homepage, the blog index, and archives are not currently supported.

Note #2: this plugin only creates AMP content but does not automatically display it to your users when they visit from a mobile device. That is handled by AMP consumers such as Google Search. For more details, see the AMP Project FAQ.

Follow along with or contribute to the development of this plugin on GitHub. For more information on the plugin, how the plugin works and how to configure and extend it, please see the project wiki.
