The simplest way to take this course is to start at Video 5 and follow along with each video, building the project as you go.
Each VideoNN_* folder contains a snapshot of the AgentClinic project as it should look at the start of that video. You don't need to copy these folders each time -- they're here so you can jump into any video without having completed the previous ones. If you want to start fresh at a specific video, just copy that folder into your own working directory:
cp -r Video06_Feature_Specification/ my-agentclinic/
cd my-agentclinic
npm installEach video folder contains the complete starter code for that video and all prompts used throughout it.
