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.

Unless otherwise noted, the go-tour source files are distributed under the BSD-style license found in the LICENSE file.

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