Is it your mission to be a dick at every opportunity?

RogerM's answer was right on the money. 100% correct and required no further commentary (especially the likes of which you just spewed out on the deck there).

Not everyone is interested in the core of CodeIgniter. The documentation covers everything you'll ever need to know as a general developer.

By the way, most of us learned this stuff by reading the docs, not digging through the core. I guess you learned PHP by reading through code that makes up the parsing engine, right?
