// Create a new StateBag bag := new(multistep.BasicStateBag) // Set a value in the bag bag.Put("myKey", "myValue") // Get the value from the bag value := bag.Get("myKey") fmt.Println(value)In this example, we first create a new `StateBag` using the `multistep.BasicStateBag` implementation. We then set a value in the bag using the `Put()` method, with a key of "myKey" and a value of "myValue". Finally, we get the value from the bag using the `Get()` method, and print it to the console. Overall, the `github.com/mitchellh/multistep` package/library provides a powerful set of tools for creating multi-step setup processes in Go. The `StateBag` type is just one of the many useful components of this package, which can help to simplify the development and maintenance of complex setup workflows.
