 **Notes:**
+* See [here](docs/random.md) for Openapi properties supported in random response generation
+* See [here](docs/static.md) for default value in static response generation
+* Regarding `--use-example` mode, property without example specified will still be randomly or statically generated
 * Random response generation can not handle recursive schema reference. If you do need it in your spec file, please provide `example` property for the recursive part of schema and specify `--use-example` option.
