Welcome to the most substantive commercial project I've ever made on any course! We will work on this project throughout the 3-week journey, culminating in a capstone that is truly enterprise grade.
This is the repo that accompanies the course. UnderCover is a fictional travel insurer. Over the three weeks we build its claims platform and an AI agent that handles claims, and in Week 3 we deploy it all to AWS.
If you're looking at this in VS Code or Cursor, right-click README.md in the Explorer on the left and choose Open Preview to see it formatted.

And in case you haven't heard it from me enough, I'd be delighted if you'd consider connecting or following on LinkedIn or subscribing on YouTube.
While about $10 of API spend would be typical for this course, there are free alternatives for everything. Most labs have a free version whose name ends in free, the installation steps include a free coding agent, and in Week 3 the free route uses Render in place of AWS.
Just ask your coding agent (Cursor, Claude Code, etc.). I've equipped it with full knowledge of the course, the labs and this project, and it can help!
I'd love to see what you build! Please share it with a pull request to community_contributions. The steps for that, and for pulling the latest code, are in guides/for_agents/AGENT_GIT_GUIDE.md, and your coding agent can take you through them.
Week 1 Day 1 is in the setup/ folder and Week 1 Day 2 is in labs/. From Week 1 Day 3 onwards we work in the entire repo. The installation steps for each day are in setup/INSTRUCTIONS.md, and the guides folder has guides to the command line, git, Python and other foundations if you'd like a refresher.
You can follow the whole course on main with your own build, without ever switching branches. On each day that we build the product with a coding agent, my version is on two branches:
week1day5-startand so on: my build so far, with the day's product brief indocs/week1day5-endand so on: my build at the end of the day
Switch to one with git checkout, for example git checkout week1day5-end. If you carry on with your own build instead, copy the day's brief from labs/ into docs/ yourself, for example labs/week1day5_product_HARNESS.md to docs/HARNESS.md.
Commit your own changes before you switch branches. Your .env file isn't in git, so it stays as it is when you switch.
