The problem is that the oath tutorial provided by Google with chrome extension is outdated (and seems to deal with oAuth not oAuth 2.0)
An almost identical question to this was asked here, however the answer simply provided an api reference, no tutorial.
I'm looking for an official (or non-official.. as long as it counts as a tutorial) for oAuth 2.0 integration with chrome extensions. Lacking that, if someone can simply give me a road map of links/tutorials where I can start at some point and reach that destination.
(Googling shows me articles like this one.. which is dated 2011, which is pretty a millennia ago)
