-==========
+# pvaDataCPP
 
-pvDataCPP is a set of data types and utilities that form part of the EPICS V4 project.
+The EPICS **pvData** API provides a set of classes and utilities that form the core of the EPICS PVA implementation.
 
+The pvDataCPP module is a part of the EPICS software toolkit that implements pvData structures as C++ class objects.
 
-Further Info

-Consult the documents in the documentation directory, in particular
-
-* pvDataCPP.html
-* RELEASE_NOTES.md
-
-Also see the [EPICS Version 4 website](http://epics-pvdata.sourceforge.net)
-
-Prerequisites
--------------
-
-The pvDataCPP  requires recent versions of the following software:
-
-1. EPICS Base (v3.14.12.3 or later)
-2. EPICS4 pvCommonCPP (4.1.0 or later)
-
-(pvCommonCPP may not be needed depending on host/compiler.)
-
-
-Building
---------
-
-Building uses the make utility and the EPICS base build system.
-
-The build system needs the location of the prerequisites, e.g. by placing the
-lines of the form
-
-    PVCOMMON = /home/install/epicsV4/pvCommonCPP
-    EPICS_BASE = /home/install/epics/base
