 Welcome to heat-translator's documentation!
-========================================================
+===========================================

+The heat-translator tool is aimed to translate non-heat templates to OpenStack
+Heat Orchestration Template (HOT). Initially the tool is aimed to translate
+OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA)
+to HOT. However, the tool can be easily extended to support any non-heat
+template format to produce HOT.
