+ There only one way to call nfv-heattranslator service: CLI.

 Step 1: Change directory to where the tosca yaml files are present, example is
 below with vRNC definiton.

-**Notes**: heat-translator will call class of ToscaTemplate in tosca-parser firstly to validate and
-parse input yaml file, then tranlate the file into hot file, if you only want to validate or
-check the input file and don't want to translate, please use tosaca-parser as following:

+nfv-toscaparser
+----------------
+
+Implementation of nfv-toscaparser derived from openstack tosca parser is based on the following OASIS specification:
+    TOSCA Simple Profile YAML 1.2 Referecne  http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.2/TOSCA-Simple-Profile-YAML-v1.2.html
+    TOSCA Simple Profile YAML NFV 1.0 Referecne  http://docs.oasis-open.org/tosca/tosca-nfv/v1.0/tosca-nfv-v1.0.html
+
+There are three ways to call nfv-toscaparser service, Python Lib ,CLI and  REST API.
+
+CLI
+****
+Using cli, which is used to validate tosca simple based service template. It can be used as:
 
 .. code-block:: bash
 
-    tosca-parser --template-file=<path to the YAML template>  [--nrpv]  [--debug]
-    or
-        tosca-parser --template-file=<path to the CSAR zip file> [--nrpv]  [--debug]
-    or
-        tosca-parser --template-file=<URL to the template or CSAR>  [--nrpv]  [--debug]
-    options:
-      --nrpv Ignore input parameter validation when parse template.
-      --debug debug mode for print more details other than raise exceptions when errors happen
+   tosca-parser --template-file=<path to the YAML template>  [--nrpv]  [--debug]
+   tosca-parser --template-file=<path to the CSAR zip file> [--nrpv]  [--debug]
+   tosca-parser --template-file=<URL to the template or CSAR>  [--nrpv]  [--debug]
 
-Example:
+   options:
+     --nrpv Ignore input parameter validation when parse template.
+     --debug debug mode for print more details other than raise exceptions when errors happen
+
+
+Library(Python)
+****************
+
+Using api, which is used to parse and get the result of service template. it can be used as:
 
 .. code-block:: bash
 
-   tosca-parser --template-file=vRNC.yaml --nrpv
+   ToscaTemplate(path=None, parsed_params=None, a_file=True, yaml_dict_tpl=None,
+                                          sub_mapped_node_template=None,
+                                          no_required_paras_valid=False, debug=False )
+
+REST API
+*********
+
+Using RESTfual API, which are listed as following:
+
+List template versions
+########################
+
+PATH: /v1/template_versions
+METHOD:  GET
+Decription: Lists all supported tosca template versions.

+If it does happen, it means the server has experienced some serious problems.
