+## Classes
 
 RMGallery handles the boilerplate of a gallery UI so you can focus in theming and implementing your custom layout. RMGallery can be used at cell, view or view controller level, each one with its own corresponding class.
 
-###RMGalleryCell
+### RMGalleryCell
 
 [`RMGalleryCell`](https://github.com/robotmedia/RMGallery/blob/master/RMGallery/RMGalleryCell.h) is a collection view cell that displays an image with zoom and panning. It keeps the image centered when smaller than the cell and sets appropiate values for the zoom scale. Zoom can be toggled on and off at specific points.
 
 The cell also has its own activity indicator view, which is animated by `RMGalleryView` while it waits for the image.
 
-###RMGalleryView
+### RMGalleryView
 
 [`RMGalleryView`](https://github.com/robotmedia/RMGallery/blob/master/RMGallery/RMGalleryView.h)  is a collection view of gallery cells in a flow layout. It has a data source (`RMGalleryViewDataSource`) that is responsible for providing images and a delegate (`RMGalleryViewDelegate`) that is notified of index changes.

 To display a full-screen gallery it's best to use `RMGalleryViewController`. If you don't need full-screen, you can use `RMGalleryView` directly.
 
-###RMGalleryViewController
+### RMGalleryViewController
 
 [`RMGalleryViewController`](https://github.com/robotmedia/RMGallery/blob/master/RMGallery/RMGalleryViewController.h) is a view controller that manages a gallery view and, much like its counterparts `UITableViewController` and `UICollectionViewController`, is designed to be subclassed.
 
 The gallery view controller gracefully handles device rotation, toggles the visibility of the status bar, navigation bar and toolbar and notifies of its own dismissal.
 
-###RMGalleryTransition
+### RMGalleryTransition
 
 [`RMGalleryTransition`](https://github.com/robotmedia/RMGallery/blob/master/RMGallery/RMGalleryTransition.h) is a default view controller transition to go from a thumnail to the gallery view controller and back, as shown in the animation above. To use it you only need to to provide the position and image of the originating thumbnail (typically, an `UIImageView`).
