Introduction to go
This document provides an introduction to the Go programming language. It discusses why a developer or operator may want to learn Go, including for open source projects, automation/scripting, or reading existing Go code. It then provides a brief overview of Go, describing it as a compiled, concurrent, garbage-collected language developed at Google for efficiency and scalability. The document also covers installing Go, important terminology, basic programming concepts in Go, and resources for learning more about Go.
