+## JSON Schema Draft Versions
+
+`jsonschema2md` assumes `draft-07` by default. If your schemas are not on `draft-07`, you can specify the draft version using the `-v` or `--draft` flag.
+
+```bash
+# run against JSON Schema Draft 04
+$ node cli.js -d examples/schemas -o examples/docs -v 04
+```
+
+```bash
+# run against JSON Schema Draft 06
+$ node cli.js -d examples/schemas -o examples/docs -v 06
+```
