 5. Create a new **Prism instance file** in the project. Name it `hello-mock.prism`.
 6. Prism instances are made up of APIs and Rules, you can learn more about them here. Add an API to the Prism instance, and connect the `hello.oas2` specification that you created earlier.

 7. Next, add a **new rule** that you will setup to power the mocking. Rules simply apply scenarios to HTTP traffic passing through the Prism instance.
 8. Once you have created a new rule, you need to connect it to the API we added earlier. To do that, click on the `apis` dropdown input, and select the previously created API.
 9. Finally, you need to add a **scenario** that will actually perform the mocking. We have an official Stoplight mock scenario [here](https://next.stoplight.io/stoplight/prism?edit=%23%2Fscenarios%2Fmock), which makes it easy to get started. Add a scenario to the `before` section of your rule. Select `another project` in the first dropdown, and then search for `prism`. The file in that project you are looking for is `helpers.prism.yml`, and the specific scenario is called `mock`. This mock scenario should suit most of your mocking use cases. For advanced use cases please send us a message and we would love to help out.

 8. **Save** your Prism instance. To verify that your mock server is working, click on the `Home` link at the top of the prism instance sidebar, and then send a test request to `GET /hello`. You should see a 200 response that equals the example you set in your OAS file earlier!
