The Go programming language is an open source project to make programmers more productive.

Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

Installing Go

Getting Started

Instructions for downloading and installing the Go compilers, tools, and libraries.

Learning Go

A Tour of Go

An interactive introduction to Go in three sections. The first section covers basic syntax and data structures; the second discusses methods and interfaces; and the third introduces Go's concurrency primitives. Each section concludes with a few exercises so you can practice what you've learned. You can install it locally with:

$ go get golang.org/x/tour

This will place the tour binary in your workspace's bin directory.

How to write Go code

This doc explains how to use the go command to fetch, build, and install packages, commands, and run tests.

Editor plugins and IDEs

A document that summarizes commonly used editor plugins and IDEs with Go support.

Effective Go

A document that gives tips for writing clear, idiomatic Go code. A must read for any new Go programmer. It augments the tour and the language specification, both of which should be read first.
