I am reading chapter 2 and in the listing 2.1, It mentioned about $Gopath . I didnt quite get what is $gopath .Is this a Environment variable ?

Also as the book did not talk about the setting up of GO I was confused in the snippet . It will be great if the setup information is provided before the chapter 2 to clarify the details.

Thanks for the feedback. Yea, I think GOPATH needs to be explain either in chapter 2 or before it. I will mark this for future edits. Thanks for taking the time to provide feedback.
