+Introduction of Parser Project
+============================
+
+In NFV, various templates (such as descriptors, records and so on) are utilized
+to describe the deployment requirements (such as basic VM requirements – vCPU,
+memory, storage, as well as the NFV acceleration management requirement such as
+Huge Pages support, SR-IOV, NUMA affinity, DPDK support etc.),
+the post-instaniation records (such as storage usage report, CPU performance
+report etc.) or other purposes. However in order to make these templates
+adaptable and feasible for purpose like deployment orchestration/automation,
+certain tooling mechanism that provides template translation is necessary.
+
+Project Parser will help to provide such tooling mechanism, by parsing Telecom
+operators’ descriptors/records into TOSCA/CAMP templates and then further
+translate TOSCA/CAMP templates into certain common templates, which could be
+used in IaaS orchestration projects like OpenStack Heat.
+
+For Release B, Parser offers the following capabilities:
+
+* Integration of Heat-Translator Liberty release code. (both heat in-tree code and standalone package are provided)
+
+* Yang2Tosca module which offers the capability to translate yang based
+scriptors to tosca formate templates. Users could further use Heat-translator
+module to translate this tosca template to Heat Orchestration template.
+Yang2Tosca module could be installed seperately after user installed
+OPNFV B release platform.
+
+* The "parser_new_keywords" document demonstrate a set of keywords concluded by
+Parser team that need to be supported in tosca to heat translation. However
+it should be noted that these keywords only serve as a roadmap. We will start
+from Release C to indicate which specific set of keywords are supported in
+Parser.
+
+* The "vRNC_tosca_intro" document describes Parser's use case analysis on vRNC scenario.
+The "example" folder contains examples of tosca-nfv standard and vRNC scenario.
