Go Tour

Go Reference

A Tour of Go is an introduction to the Go programming language. Visit https://tour.golang.org to start the tour.


To install the tour from source, first install Go and then run:

$ go get golang.org/x/tour

This will place a tour binary in your workspace's bin directory. The tour program can be run offline.


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

To run the tour server locally:

go run .

Your browser should now open. If not, please visit http://localhost:3999/.

Report Issues / Send Patches

This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.

The issue tracker for the tour's code is located at https://github.com/golang/go/issues. Prefix your issue with “x/tour:” in the subject line, so it is easy to find.

Issues with the tour's content itself should be reported in the issue tracker at https://github.com/golang/tour/issues.


  1. To deploy tour.golang.org, run:

    GO111MODULE=on gcloud --project=golang-org app deploy --no-promote app.yaml

    This will create a new version, which can be viewed within the golang-org GCP project.

  2. Check that the deployed version looks OK (click the version link in GCP).

  3. If all is well, click “Migrate Traffic” to move 100% of the tour.golang.org traffic to the new version.

  4. You're done.
