In May, we announced Instant Articles, a fast and interactive experience for reading articles in News Feed. Beyond creating a great experience for readers, we designed Instant Articles to make it as easy as possible for publishers to use with their existing Content Management Systems (CMS). Today, we’re sharing more about the system for publishing Instant Articles, which is based on the open standards that power the web, and introducing documentation for publishers and tool providers. You can read more about this on the Facebook Developer Blog.

We are also announcing that we are expanding the test to more people and publishers. Over the coming months we will be expanding the number of people in the Facebook app on iPhone who can see Instant Articles, and we will bring more publishers on board, including over a dozen joining the program soon. We look forward to extending the Instant Articles program broadly to even more people and publishers in the future.
