-##### Override the Working Directory
-
-By default, `rdme` bundles all [references](https://swagger.io/docs/specification/using-ref/) with paths based on the directory that `rdme` is being run in. You can override the working directory using the `--workingDirectory` option, which can be helpful for bundling certain external references (see [here](__tests__/__fixtures__/relative-ref-oas/petstore.json) for an example file).

-```sh
-rdme openapi petstore.json --workingDirectory=[path to directory]

 #### Validating an API Definition
 
 You can also perform a local validation of your API definition (no ReadMe account required!), which can be useful when constructing or editing your API definition.
