+## Passing Arguments as Objects
+All OPC components can also be created by passing an object of arguments, such as below. This also allows passing in additional parameters [label, description].
+```javascript
+OPC.slider({
+	name: 'stroke_weight',
+	value: 3,
+	min: 1,
+	max: 10,
+	step:1,
+	label: 'Circle Border',
+	description: 'Changes the border size of the circle'
+});
+```
+Note that, the object values are copied and are **not** referenced; Changing the object arguments at a later time will not effect the OPC component.
