+   - `[script]` Any script in the template's [package.json](/packages/create-bison-app/template/package.json.ejs). By default, the `dev` script is run.
    - `--acceptDefaults` Skip interactive prompts and use default options to create a new Bison app
    - `--clean` When running `yarn dev` subsequent times, use this to reconfigure and create a new Bison app
-   - `--port` Specify the port to listen on. Defaults to 3001.
 
-Example:
+### Example Usages
+
+Start the development server:
+
+```
+yarn dev --acceptDefaults --clean
+```
+
+Run the `test` script in Bison's [package.json](/packages/create-bison-app/template/package.json.ejs):

 ```
-yarn dev --acceptDefaults --clean --port=5000
+yarn dev test
