+Open Source Software Experiance Camp 2018 in KNU 
+================================================
+
+ Dear KNUCSE & participants related to this camp,
+
+For testing, I edited some files and moved all related sources
+to this directory.
+
+I did it for the convenience of everyone.
+but, if you don't want this `Change <https://review.openstack.org/#/c/607559>`_
+, Please contact me by
+`E-Mail <ardentpark@gmail.com>`_.
+
+Then, I'll revert it if necessary.
+
+Thank you.
+
+ **Innovation! KNUCSE!**
