Does the method return anything? What is the amount of points? The instructions were a little scarce on this one. Help

Am I supposed to add a return value? Or not? Also, how many points do I increment by. Or does the user decide the amount of "points" to increment by?. Please help, the instructions left out a little bit of detail in my opinion.. Thank you !

Button.swift
```class Button {
var width: Double
var height: Double

init(width:Double, height:Double){
self.width = width
self.height = height
}

func incrementBy(points : Int){

}

}
```

Hello Collin:

Challenge:

We need to provide a means to increase the size of our Button. So we are going to add a method named incrementBy which will accept a parameter named points. (Within the method add points to the width and height properties).

lets break it down..

So we are going to add a method named incrementBy which will accept a parameter named points

```func incrementBy(points: Double){}
```

Within the method add points to the wide and height properties

```func incrementBy(points: Double){
width += points // these are the properties
height += points
}

// We are using the local parameter name (points) to implement the method
```

This is how the challenge will look

```class Button {
var width: Double
var height: Double

init(width:Double, height:Double){
self.width = width
self.height = height
}

func incrementBy(points: Double){
width += points
height += points
}
}
```

Hope this helps you understand a bit better, please let me know if you have any questions

Good luck
