Hi, I recently downloaded the developer edition of the ESRI Web AppBuilder here and I am trying to build a new widget using the sample here. I can get through the first three steps but on Step 4 it tells me to " Open the config-demo.json file in the stemapp/sample-configs folder. Find widgetPool->widgets, and add a new widget element like this. Save the file." These files don't exist in my download, I don't have any file named config-demo.json, and I don't have a sample-configs demo folder. Am I looking at the wrong thing or am I supposed to create these folders?
