-<Feature> capabilities and usage
-================================
-Describe the specific capabilities and usage for <XYZ> feature.
+Installation
+============================
 
-<Feature and API usage guidelines and example>
------------------------------------------------
-Describe with examples how to use specfic features.
+Please follow the below installation steps to install parser.
 
+Step 1: Clone the parser project.
+
+.. code-block:: bash
+
+    git clone https://gerrit.opnfv.org/gerrit/parser
+
+Step 2: Install the heat-translator sub project.
+
+.. code-block:: bash
+
+    # uninstall pre-installed tosca-parser
+    pip uninstall -y heat-translator
+
+    # change directory to heat-translator
+    cd parser/tosca2heat/heat-translator
+
+    # install requirements
+    pip install -r requirements.txt
+
+    # install heat-translator
+    python setup.py install
+
+Step 3: Install the tosca-parser sub project.
+
+.. code-block:: bash
+
+    # uninstall pre-installed tosca-parser
+    pip uninstall -y tosca-parser
+
+    # change directory to tosca-parser
+    cd parser/tosca2heat/tosca-parser
+
+    # install requirements
+    pip install -r requirements.txt
+
+    # install tosca-parser
+    python setup.py install
+
+
+  **Notes** It must uninstall pre-installed tosca-parser and heat-translator before install the two
+  components, and install heat-translator before installing tosca-parser, which is sure to use the
+  OPNFV version of tosca-parser and heat-translator other than openstack's components.
+
+Execution
+===========================
+
+Step 1: Change directory to where the tosca yaml files are present, example is
+below with vRNC definiton.
+
+.. code-block:: bash
+
+    cd parser/tosca2heat/tosca-parser/toscaparser/extensions/nfv/tests/data/vRNC/Definitions
+
+
+Step 2: Run the python command heat-translator with the TOSCA yaml file as an input option.
+
+.. code-block:: bash
+
+    heat-translator --template-file=<input file> --template-type=tosca
+                    --outpurt-file=<output hot file>
+
+Example:
+
+.. code-block:: bash
+
+    heat-translator --template-file=vRNC.yaml \
+        --template-type=tosca --output-file=vRNC_hot.yaml
+
+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:
+
+.. code-block:: bash
+
+   tosca-parser --template-file=<input yaml file>
+
+Example:
+
+.. code-block:: bash
+
+   tosca-parser --template-file=vRNC.yaml

+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.
