 Parser tosca2heat
 =================
 
+Tosca2heat is a opnfv sub-project of parser based on openstack two projects: tosca
+parser and heat translator.
+
+The TOSCA Parser 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.
+Heat-Translator is a command line tool which takes non-Heat templates as an input
+and produces a Heat Orchestration Template (HOT) which can be deployed by Heat.
+
+More details please refer to openstack related sites.
+
+Tosca2heat intends to enhanced NFV features in tosca template parse and translator,
+such as huge page, dpdk and sriov.
