I'm new to Go. I've installed ActiveGo. How do I get started?
The introduction will explain how your workspace is arranged. In case you missed it, your $GOPATH has already been set by the ActiveGo installer.
If you don't use Git already, you should install it and learn how to use it. Git is an essential supporting tool for coding in Go.
There's a simple HelloWorld program in the Go introduction.
ActiveGo sets up local documentation on your system as a document server. On the local ActiveGo documentation start page, there is an interactive Sandbox window labelled "Try Go". You will see the source code before it compiles. When you click "Run" the code compiles and displays the result in the box below the source code. There's a pull-down with a small set of sample Go snippets.
