 Parser Configuration and Configuration Guide
 ********************************************
+Parser is an open source project and licensed under Apache 2. Parser will help
+to provide a tooling mechanism, by parsing and then further translating Telecom
+operators deployment descriptors into certain common templates, which could be
+used in IaaS orchestration projects like OpenStack Heat(the template file is HOT,
+which stands for Heat Orchestrator Template).
+
+This document contains configuration guide for Parser's three submodules: tosca2heat,
+yang2tosca and policy2tosca. Users please refer to user guide for installation and execution
+which usually happens after configuration.

+Step 2: Copy the YANG file which needs to be converted into TOSCA to

+
+Step 3: Run the python script "parser.py" with the YANG file as an input option.

 Parser User Guide
 =================
 Parser is an open source project and licensed under Apache 2. Parser will help
-to provide a tooling mechanism, by parsing Telecom operators VNF descriptors
-(YANG templates) into TOSCA templates and then further translate TOSCA templates
-into certain common templates, which could be used in IaaS orchestration projects
-like OpenStack Heat(the template file is HOT, which stands for Heat Orchestrator
-Template), this document is about simple TOSCA to HOT, and the example is a vRNC
-(virtual Radio Network Controller) definition with format translated from simple
-TOSCA(parser's input file format) to HOT(parser's output file format), which can
-be deployed by heat directly.
