Starting from https://www.mongodb.com…

• Products… Tools… Mongoose ODM Support is listed but no mention of Mongoid or any other driver.
• Resources… Documentation… Drivers… Neither Mongoose nor Mongoid are listed.
• Browsing into Ruby, we have a getting started guide that goes into detail on how to install the Ruby Driver. Only at the very bottom of the page we finally see “For tutorials on Mongoid, see the Mongoid Manual.”
• Following this link, we land on a very user unfriendly table of contents for the upcoming version.
