+
+When you develop a new template, action or new `<ScaffolderFieldExtensions/>`, then we recommend

+
+To play with it, open a terminal and run the command: `yarn start` within the `./plugins/scaffolder` folder
+
+**NOTE:** Don't forget to open a second terminal and to launch the backend or [backend-next](../../docs/backend-system/index.md) there, using `yarn start` and to specify the locations of the templates to play with !
