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.
Instructions for downloading and installing the Go compilers, tools, and libraries.
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 take the tour online or install it locally.
How to use the go command to fetch, build, and install packages, commands, and run tests.
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.

The talks marked with a red asterisk (*) were written before Go 1 and contain some examples that are no longer correct, but they are still of value.
A talk by Rob Pike and Andrew Gerrand presented at Google I/O 2011. It walks through the construction and deployment of a simple web application and unveils the Go runtime for App Engine. See the presentation slides.
A talk by Andrew Gerrand presented at Google I/O Bootcamp 2011. It gives a broad overview of Go's type system and concurrency model and provides four examples of Go programs that solve real problems. See the presentation slides.
A talk by Andrew Gerrand presented at Google Developer Day Japan 2011. It discusses the development of a web application that runs on Google App Engine and renders images that it stores on Google Cloud Storage.
A presentation delivered by Rob Pike and Russ Cox at Google I/O 2010. It illustrates how programming in Go differs from other languages through a set of examples demonstrating features particular to Go. These include concurrency, embedded types, methods on any type, and program construction using interfaces.
This talk presents the development of a complete web application in Go. It looks at design, storage, concurrency, and scaling issues in detail, using the simple example of an URL shortening service. See the presentation slides.
