-* For setup, pull in the changes from the `phase4` branch.
+* For setup, merge in the changes from the `phase4` branch.
   * It adds chaos-injecting code in `Program.cs` to simulate random failures in downstream API calls.
   * Execute a couple of requests with increasing ids until an error happens.
-* Implement resiliency measures to handle these kinds of failures.
+* Implement basic resiliency measures to handle these kinds of failures.
 * **Success Criteria: Check the service logs to see the resiliency measures in action.**
