Docs are maybe better hidden than those options. And quite many of us are more or less just selfmade webmasters who needs very strong ironwire as helps, I reckon. Rails or what ever gems here are in use, are actually quite rare systems compared to more common PHP-world. That means one really important thing: when googling one can find texts only from devs to devs. That’s why so many is wondering how to get some strange console to work.
(Same reason why Jekyll etc are so rare out there)
