+Parser yang2tosca Execution
+============================
+
+Step 1: Change directory to where the scripts are present.
+
+.. code-block:: bash
+
+    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.
+
+.. code-block:: bash
+
+    python parser.py -n "YANG filename"
+
+Example:
+
+.. code-block:: bash
+
+    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.
+
+.. code-block:: bash
+
+    cat "YANG filename_tosca.yaml"
+
+Example:
+
+.. code-block:: bash
+
+    cat example_tosca.yaml

+Parser policy2tosca Execution
+============================
+
+Step 1: To see a list of commands available.
+
+.. code-block:: bash
+
+    policy2tosca --help
+
+Step 2: To see help for an individual command, include the command name on the command line
+
+.. code-block:: bash
+
+    policy2tosca help <service>
+
+Step 3: To inject/remove policy types/policy definitions provide the TOSCA file as input to
+policy2tosca command line.
+
+.. code-block:: bash
+
+    policy2tosca <service> [arguments]
+
+Example:
+
+.. code-block:: bash
+
+    policy2tosca add-definition --policy_name rule2 --policy_type  tosca.policies.Placement.Geolocation
+--description "test description" --properties region:us-north-1,region:us-north-2,min_inst:2 --targets
+VNF2,VNF4 --metadata "map of strings" --triggers "1,2,3,4" --source example.yaml
+
+
+Step 4: Verify the TOSCA YAMl updated with the injection/removal executed.
+
+.. code-block:: bash
+
+    cat "<source tosca file>"
+
+Example:
+
+.. code-block:: bash
+
+    cat example_tosca.yaml
