+# Configuration Persistence Service
+
+This folder contains all files for
+[Configuration Persistence Service](https://wiki.onap.org/pages/viewpage.action?pageId=81406119).
+
+The code here is related to CPS POC, then it must be kept self contained in this cps folder to prevent any impact on
+current ccsdk components and to be ready to be moved in its own repo once CPS becomes a standalone project.
+
+
