-# YGOPro in Unity
+# You have just found ygopro v2 in Unity 3D!
 
-This is only a temp readme in chinese. Later there will be a fine readme in many languages.
+YGOPro v2 is a card simulation game created in Unity Engine, with same protocol to ygopro.
+The game is now being tested in china now, with at least *100,000* users ( about *30%* active users ), which is calculated from the downloads of our weekly updating packages.
+We use Yu-Gi-Oh card game only to test our engine, and the game is not for commercial use. When our card game engine is finally finished in about several years, all the contents about Yu-Gi-Oh will be deleted.
 
-这个很傻的说明是暂时的，以后会改。
-要给star哦。
