A Tour of Go is an introduction to the Go programming language.
The easiest way to install the tour locally is to install a binary release of Go and then run:
$ go tool tour
To install the tour from source, first set up a workspace and then run:
$ go get golang.org/x/tour/gotour
This will place a gotour binary in your workspace's bin directory.

Contributions should follow the same procedure as for the Go project: https://golang.org/doc/contribute.html
