+TOSCA Parser
+===============
+
+Overview
+--------
+
+The TOSCA Parser is an OpenStack project and licensed under Apache 2. It is
+developed to parse TOSCA Simple Profile in YAML. It reads the TOSCA templates
+and creates an in-memory graph of TOSCA nodes and their relationship.
+
+Architecture
+------------
+
+The TOSCA Parser takes TOSCA YAML template or TOSCA Cloud Service Archive (CSAR)
+file as an input, with optional input of dictionary of needed parameters with their
+values, and produces in-memory objects of different TOSCA elements with their
+relationship to each other. It also creates a graph of TOSCA node templates and their
+relationship.
+
+The ToscaTemplate class located in the toscaparser/tosca_template.py is an entry
+class of the parser and various functionality of parser can be used by initiating
+this class. In order to see an example usage of TOSCA Parser from a separate tool,
+refer to the OpenStack heat-translator class TranslateTemplate located in the
+translator/osc/v1/translate.py module. The toscaparser/shell.py module of tosca-parser
+also provides a good reference on how to invoke TOSCA Parser from Command Line Interface.
+
+The toscaparser/elements sub-directory contains various modules to handle
+various TOSCA type elements like node type, relationship type etc. The
+entity_type.py module is a parent of all type elements. The toscaparser
+directory contains various python module to handle service template including
+topology template, node templates, relationship templates etc. The
+entity_template.py is a parent of all template elements.
