+Parser YANG2TOSCA
+========================
+
+Overview
+===========================
+
+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.
+
+Prerequisites
+==========================
+
+Parser requires the following to be installed.
+
+1. PYANG
+-----------------
+
+Please follow the below installation steps.

+                                or
+                wget https://github.com/mbj4668/pyang/archive/master.zip
+
+Step 2: Change directory to the downloaded directory and run the setup file.
+                cd pyang

+============================
+
+Please follow the below installation steps to install parser.
+
+Step 1: Clone the parser project.
+        git clone https://gerrit.opnfv.org/gerrit/parser
+
+Execution
+===========================
+
+Step 1: Change directory to where the scripts are present.
+        cd parser/yang2tosca
+
+Step 2: Copy the YANG file which needs to be converted into TOSCA to
+        current (parser/yang2tosca) folder.
+
+Step 3: Run the python script "parser.py" with the YANG file as an input option.
+                python parser.py -n "YANG filename"
+        Example:
+                python parser.py -n example.yaml
+
+Step 4: Verify the TOSCA YAMl which file has been created with the same name
+        as the YANG file with a “_tosca” suffix.
+                cat "YANG filename_tosca.yaml"
+        Example:
+                cat example_tosca.yaml
