-Your workshop app
-A local application shell with supplied hosting helpers ready for the next lesson.
+Your first coach in DevUI
+Your ChatClientAgent uses a Foundry model and answers in DevUI.
 
-Checkpoint: 02-starter
+Checkpoint: 03-first-coach
 Source tag: workshop-v3-reference.1
 Reference revision: 443eac269743643d1bd5a35582fa3fac27bc6ad5
 Workshop profile: foundry-workshop-v3
 
-Extract interview-coach-lab-starter.zip into interview-coach-lab once. Continue editing that folder throughout the course.
+This is an optional recovery/comparison checkpoint. Extract into a separate folder and keep your existing work.
 The Chapter 0 example lives in interview-coach-example.
 Setup and resource guidance: https://codemillmatt.github.io/interview-coach-agent-framework/workshop/00-orientation/
 Run from this directory: aspire start --apphost ./apphost.cs
-This application shell runs without cloud resources. Configure reuse of the Chapter 0 model before activating it in Chapter 2.
+Configure reuse of the Chapter 0 account and model deployment before starting. Model calls cost money; confirm the subscription and cleanup owner.
 Use the root AppHost throughout the course. Keep WorkshopHosting.cs and the MCP discovery probe.
 Chapter 13 practices debugging with the completed application. Chapter 14 reviews the workshop.
 Prepare the separate project-based AppHost only for optional deployment: https://codemillmatt.github.io/interview-coach-agent-framework/resources/deployment/
