+Test the heat-translator translation from command line as:
+#heat-translator
+ --template-file=<path to the YAML template>
+ --template-type=<type of template e.g. tosca>
+ --parameters="purpose=test"
+Takes three user arguments,
+1. type of translation (e.g. tosca) (required)
+2. Path to the file that needs to be translated (required)
+3. Input parameters (optional)
+
+In order to use heat-translator to only validate template,
+without actual translation, pass --validate-only=true along with
+other required arguments.
