 ## Initial Configuration
 
+Within a new or existing Django or wq project, configure the following:
+
+ 1. Celery / Redis
+ 2. A model for (up)loading source data
+ 3. One or more serializers for populating the destination models
+ 4. wq/progress.js plugin (if using wq)

 ### Celery

 At least one serializer should be registered in order to use the wizard.  Note the use of a human-friendly serializer label when registering.  This name should be unique throughout the project, but can be changed later on without breaking existing data.  (The class path is used as the actual identifier behind the scenes.)
 
+### Progress Bar Support
+
+If you are using the built-in Data Wizard interface for wq, be sure to enable the [wq/progress.js] plugin.
+
+```javascript
+// myapp/main.js
+define(['wq/app', 'wq/progress', ...],
+function(app, progress, ...) {
+    app.use(progress);
+    app.init(config).then(...);
+});

 ## Run-Time Usage (REST API)
 
 The Data Wizard REST API provides the following capabilities.  If you are using wq.db, the wizard will automatically register itself with the router.  Otherwise, be sure to include `data_wizard.urls` in your URL configuration:
