Good : Google's documentation - It nicely break downs documentation into 3 or 4 simple tabs(guides, reference and samples). Left panel has breakdown of page related to tab , right panel has more detailed view of the page itself. This kind of provides 3-indices to entire documentation. (eg: https://goo.gl/7ZIuX https://goo.gl/7ZIuX) Most of documentation is simple enough to understand with examples and highlighted with right colors wherever it is required (I feel color highlighting remains under appreciated in documentation). And also one can invoke apis and play a bit. Bad : mongoose.
