+Then, there are multiple ways you can create NVActivityIndicatorView:
 
 - Use it in storyboard by changing class of any `UIView` to `NVActivityIndicatorView`
 This will use default values 40, white, .Pacman for size, color and type respectively.
 
-- Create with specified type and size 40, color white as default
+- Create with specified type, color and size
 
 ```swift
-NVActivityIndicatorView(frame: frame, type: type)
+NVActivityIndicatorView(frame: frame, type: type, color: color, size: size)
 ```
 
-- Create with specified type, color and size 40 as default
+Any of the last three arguments can be omitted. If an argument is omitted it will use the default values which are 40, white, .Pacman for size, color and type respectively.
+Therefore, you can also create NVActivityIndicatorView using any of the following:
 
+- specify only frame, type and color
 ```swift
 NVActivityIndicatorView(frame: frame, type: type, color: color)
 ```
 
-- Create with specified type, color, size
