 #ioLibrary Driver
 The ioLibrary means “Internet Offload Library” for WIZnet chip. It includes drivers and application protocols. 
-The driver (ioLibrary) can be used for [W5500](http://wizwiki.net/wiki/doku.php?id=products:w5500:start) application designs. These will be updated continuously.
+The driver (ioLibrary) can be used for the application design of WIZnet TCP/IP chips as [W5500](http://wizwiki.net/wiki/doku.php?id=products:w5500:start), W5200, W5100 and etc.

 ##ioLibrary
 This driver provides the Berkeley Socket type APIs.

 ## How to add an ioLibrary in project through github site.
  - Example, refer to https://www.youtube.com/watch?v=mt815RBGdsA
+  - [ioLibrary Doxygen doument](https://github.com/Wiznet/ioLibrary_Driver/blob/master/Ethernet/SOCKET_APIs_V2.0.chm) : Refer to **TODO** in this document
+    - Define what chip is used in **wizchip_conf.h**

 ## Revision History
-Last release : Nov. 2014
+  * Type casting error Fixed : 09, April. 2015
+    In socket.c, send() : Refer to M20150409
+  * ioLibrary V2.0 released : April. 2015
