+### Options
+
+The share button can be disabled by passing a flag in to the constructor to specify this:
+```swift
+let webVC = SwiftWebVC(urlString: "http://google.com", sharingEnabled: false)
+```
+The same principal applies for the modal implementation also:
+```swift
+let webVC = SwiftModalWebVC(urlString: "http://google.com", sharingEnabled: false)
+```
+
+#### Modal Options Only
+Themes may be chosen for the modal implementation. The default theme is `Light-Blue`. Other modal themes `Light-Black` and `Dark` may be chosen using one of the following instead:
 
 ```swift
 let webVC = SwiftModalWebVC(urlString: "http://google.com", theme: .lightBlack)
 let webVC = SwiftModalWebVC(urlString: "http://google.com", theme: .dark)
 ```

 ## Delegate (Start/Finish Loading Callbacks)
 
 SwiftWebVC also includes a delegate protocol that allows you to implement `didStartLoading` and `didFinishLoading` functions to determine when loading starts and finishes.
