 ## Layout Direction
 
+Layout direction specifies the direction in which children and text
+in a hierarchy should be laid out. Layout direction also effects what
+edge `start` and `end` refer to. By default Yoga lays out with `LTR`
+layout direction. In this mode `start` refers to `left` and `end`
+refers to `right`. When localizing your apps for markets with RTL languages
+you should customize this by either by passing a direction
+to the `CalculateLayout` call or by setting the direction on the root node.
+
+**LTR (DEFAULT)** Text and children and laid our from left to right. Margin and
+padding applied the start of an element are applied on the left side.
