Welcome to the new Ghost editor - affectionately known as Koenig.\n\nKoenig is a brand new writing experience within Ghost, and follows more of a\nrich writing experience which you\'ve come to expect from the best publishing\nplatforms.

You can still use Markdown too, if that\'s what\nyou prefer.\n\nBecause there are some changes to how Ghost outputs content using its new\neditor, we dropped this draft post into your latest update to tell you a bit\nabout it – and simultaneously give you a chance to preview how well your theme\nhandles these changes. So after reading this post you should both understand how\neverything works, and also be able to see if there are any changes you need to\nmake to your theme in order to upgrade to Ghost 2.0.\n\n\n--------------------------------------------------------------------------------\n\nWhat\'s new\nThe new editor is designed to allow you have a more rich editing experience, so\nit\'s no longer limited to just text and formatting options – but it can also\nhandle rich media objects, called cards.
