 ```bash
 serverless deploy [--no-delete-contents] [--no-generate-client]

+Serverless v3 cli params
+
+> Serverless v3 forbids free-form cli options.  
+> Therefore options can now only be passed as `--param="option=value"`.  
+> For the sake of simplicity, all v2 options are still available and passable through the `param` argument.  
+
+```bash
+serverless deploy [--param="no-delete-contents"] [--param="generate-client"]
+```

 The plugin should output the location of your newly deployed static site to the console.
 
 **Note:** *See [Command-line Parameters](#command-line-parameters) for details on command above*
