Whoever is maintaining the blog/website could probably make things like this clearer by placing a 404 or a Page Moved placeholder here (preferably with note that it moved and an option to redirect to the legacy docs, changes like this take minutes to make not hours or days) because it's simply /not/ user friendly as is.
I'm sure plenty of people like me installed, started a workflow and then haven't had to go back for changes until months later because they wanted to tweak one setting.
This is not your problem per se Stevi but I'm averse to updating my version because I don't know what changes were made and the lack of a full length guide makes me think the settings I had are going to change / go away which is not encouraging.
