-## Overview
-SnapLayout offers many `UIView` extension methods available in the [source files](SnapLayout/SnapLayout/Classes/SnapLayout.swift). 
+## Usage

+### Overview 
 
 * All methods are prefixed with `snap` for quick Xcode autocomplete.
 * Directly uses NSLayoutAnchor under the hood so the API is developer friendly
-* Any view using `SnapLayout` will not only have its `translatesAutoresizingMaskIntoConstraints` set to false, but also have its constraint activated.

 * Amazing constraint situations such as snapping a button to the label on top of it is an effortless process now: `button.snapVertically(topView: label, constant: 8)`

 ### [`UIView`](SnapLayout/Classes/SnapLayout.swift) extension methods
 ```swift
 func snap(to view: UIView? = nil, top: CGFloat? = nil, leading: CGFloat? = nil, bottom: CGFloat? = nil, trailing: CGFloat? = nil, width: CGFloat? = nil, height: CGFloat? = nil, centerX: Bool? = nil, centerY: Bool? = nil)
