On the Symfony blog there's a new post introducing the new project documentation, the result of lots of work from a large number of developers to bring the framework's documentation up to date.

When the Symfony documentation was started more than 5 years ago, it was just a few short articles written by Fabien. Now, we boast more than 1,000 pages of documentation, a team of 4 maintainers and over 1,000 contributors!

As the project grew, we've tried to innovate: adding continuous integration to catch build errors, setup Platform.sh to auto-deploy every pull request and implemented a process so that all new features to Symfony's core become documented (an amazingly rare feat).

And just like with code, a project must challenge itself continuously to stay ahead of the curve. In this article, we're thrilled to introduce the new Symfony Documentation: a result of over 150 hours of volunteer work via a secret project codenamed "Project Mercury".

They talk about some of the challenges they faced with the previous version of the documentation and some of the problems they wanted to solve. Instead of splitting things up into three sections ("Book", "Cookbook" and "Components") they opted to break it up into something more approachable for two different categories of users: "Getting Started" and "Guides" (everything else). They share some about how they made this new version happen and the workflow they followed to keep everything (and everyone) in sync.

You can check out this new documentation over on the completely revamped documentation site right now.
