 1. Give your mock sever a name
 2. You can select an optional environment to have your mock sever use environment variables. See Postman_environment_variables.md for details.
 3. You can also configure a delay before the mock server sends responses to simulate network delays.
 4. If you choose to make your mock server private, you need to add a [Postman API key](https://learning.postman.com/docs/developer/postman-api/intro-api/) in the request header when sending requests to the mock server: x-api-key:<Your-Postman-API-key>. If you share the collection, others can use their Postman API keys to make calls to the mock server.

+## Conclusion
+If the APIs to be used in Production are still in development or we want to avoid sending requests on real time data, a mock server can be very useful.
+A Postman mock server can simulate real API features with examples, verify APIs with mocking data, and help developer to identify errors and dependencies in API before it is released for actual usage. After reading the instruction, you should be able to set up and use your own Postman mock server.
