For those that didn't attend the symposium, beside the big Sitecore 9 news and release, we also got a new and improved documentation website!

The brand new documentation site can be found here https://doc.sitecore.net/developers.
New Sitecore documentation

Most of the links on the documentation website will go to either the new documentation platform or the old one.
For example everything about xConnect can be found here: https://doc.sitecore.net/developers/xp/getting-started/


As you can see, this is a new site with a clean, crisp menu on the left and a documentation pane on the right.
For those interested, the documentation sites are created with Sphinx and is hosted on Readthedocs.
