+Currently, the full functionality is only available through the browser. When

+The following example illustrates the use of QuaggaJS within a node
+environment. It's almost identical to the browser version with the difference
+that node does not support web-workers out of the box. Therefore the config
+property `numOfWorkers` must be explicitly set to `0`.
