this is a great question!

going to disappoint in saying that you can't read most online documentation cover to cover. i don't know of any that works that way. (unless it's the guide or tutorial part.)

you can use the online documentation as reference though. presumably a book or a guide has already told you about the packages/interfaces/functions/etc. you are looking for.

i have to say that go is one of the best documented language out there. "go doc" should be all one needs if we were all serious about documenting go code/libraries.
