Example from Getting Started section doesn't run

The following example from Getting Started section doesn't run as is.

package main

import (
	"fmt"
	"github.com/benmanns/goworker"
)

func myFunc(queue string, args ...interface{}) error {
	fmt.Printf("From %s, %v\n", queue, args)
	return nil
}

func init() {
	goworker.Register("MyClass", myFunc)
}

func main() {
	if err := goworker.Work(); err != nil {
		fmt.Println("Error:", err)
	}
}

It prints "Error: you must specify at least one queue". Perhaps updating this code so newcomers can execute it without further knowledge would be a good idea.
