After realizing I could learn more about Stack Exchange, I started googling "Stack Exchange Guide", so I could learn more about the different Stack Exchange sites and start branching out my questions from Stack Overflow.
In the process, I found this WikiBook: The Stack Exchange User Guide
The author is "benonsoftware", but I am not sure if there's a connection.
I wanted to see if it's legitimate and/or there will be more to come in the future? I think this is a cool idea whether Stack Exchange created or user-created.
