 `domNode` | `Element`, **REQUIRED** if `dom_id` is not provided. The HTML DOM element inside which SwaggerUi will put the user interface for swagger. Overrides `dom_id`.
 `spec` | `Object={}`. A JS object describing the OpenAPI Specification. When used, the `url` parameter will not be parsed. This is useful for testing manually-generated specifications without hosting them.
 `url` | `String`. The url pointing to API definition (normally `swagger.json` or `swagger.yaml`). Will be ignored if `urls` or `spec` is used.
-`urls` | `String`. An array of API definition objects (`{url: "<url>", name: "<name>"}`) used by Topbar plugin. When used and Topbar plugin is enabled, the `url` parameter will not be parsed. Names and URLs must be unique among all items in this array, since they're used as identifiers.
+`urls` | `Array`. An array of API definition objects (`[{url: "<url1>", name: "<name1>"},{url: "<url2>", name: "<name2>"}]`) used by Topbar plugin. When used and Topbar plugin is enabled, the `url` parameter will not be parsed. Names and URLs must be unique among all items in this array, since they're used as identifiers.
 `urls.primaryName` | `String`. When using `urls`, you can use this subparameter. If the value matches the name of a spec provided in `urls`, that spec will be displayed when Swagger-UI loads, instead of defaulting to the first spec in `urls`.
