-### Exercise 6: Refactor the code to follow REST principles
+### Exercise 6: Adding in Swagger
+
+Lets now add in Swagger to the project. This will involve installing the following dependency `springfox-boot-starter`. The version should be `3.0.0`.
+
+Ask Copilot how you could achieve this. You can use the `@workspaces` command to give Copilot the context of the structure of the whole repo.

+### Exercise 7: Refactor the code to follow REST principles
 
 At this point in the previous exercises, we created a number of endpoints that are not following REST principles. Let's refactor the code to follow REST principles. You should also update the Swagger documentation, so that each endpoint has a summary and is grouped using tags.
 
 Ask Copilot how you could achieve this. You can use the `@workspaces` command to give Copilot the context of the structure of the whole repo.
 
-### Exercise 7: Document the code
+### Exercise 8: Document the code
 
 Documenting code is always a boring and painful task. However, we can use Copilot to document it for us. In the chat, ask Copilot to add javadoc to all of your files.
 
 You can use `@workspaces` to write documentation for the whole repo.
 
-### Exercise 8: Verify Tests
+### Exercise 9: Verify Tests
 
 Have you been building your Unit Tests along the way? If not this is the perfect time to take a breather and get Copilot to write some unit tests for you!
 
 We will create automated tests to check that the functionality of the previous endpoints is correctly implemented. The tests should be together in the `CopilotDemoApplicationTests.java` file.
 
 You can leverage Copilot to run the tests. There is a `/tests` command that you can directly run from Copilot Chat or by selecting the piece of code you want to create tests for and using the Copilot inline feature.
 
-### Exercise 9: Create a Dockerfile
+### Exercise 10: Create a Dockerfile
 
 Use the Dockerfile provided to create a docker image of the application. There are some comments in the Dockerfile that will help you to complete the exercise.
