+
+2- connect an outlet to it, call it `viewProcess`
+
+3- create options object and assign it to `viewProcess` :
+
+```Swift
+let step = 3
+let totalSteps = 4
+        
+var options = ProcessOptions()
+options.setNumberOfItems(number: totalSteps)
+options.images = [(img1, nil), (img2, nil), (img3, nil), (img4, nil)]
+options.stepComplete = step
+options.bgColor = bgColor
+viewProcess.options = options
+```
+# note
+* set the number of process steps through options's `setNumberOfItems` method.
+* `options.images` should be assigned an array it's count equals to the total number of steps.
