A workshop run at the Australian National University, designed for second-year computer science students. This covers some high-level ideas in Go (primarily focused on concurrency), and provides some exercises to work on. It assumes the reader has gone through the Tour of Go.
Secondly, set up an IDE of your choice. I personally use Visual Studio Code with the Golang extension.
Another good option is GoLand, an IDE built by Jetbrains. If you've used IntelliJ IDEA before (such as in COMP1110), this should be familiar to you.
