+# jButtonFlash
+
+### [Download Latest](https://github.com/fondlez/jButtonFlash/releases/latest)
+
+This is a backport of the jButtonFlash addon from the Legion game version. It
+supports the final version clients for Warlords of Draenor (WoD 6.2.4), Mists 
+of Pandaria (MoP 5.4.8), Cataclysm (Cata 4.3.4) and Wrath of the Lich King 
+(WotLK 3.3.5a).
+
+* This backport is by [fondlez](https://github.com/fondlez/jButtonFlash).
+* Original addon is by [jwldnr](https://github.com/woldner/jButtonFlash).
+
+## Description
+This simple addon adds an animation to highlight a button on the action bar when 
+pressed. 
+
+It is inspired by the old and outdated addon "SnowFallKeyPress", which
+was made mostly obsolete when the Cataclysm expansion was launched due to the 
+new Interface Combat option called "Cast action keybinds on key down". However, 
+the remaining function that highlighted buttons on keypress was missed by many. 
+This addon returns that feature in a similar way.
