Kickstart a new Rails project with opinionated defaults. Use when user wants to set up a new project.
Check where you ar in the process. If Section 2 setup is not yet complete you need to do that first. Otherwise, if Section 2 is done and you're in a devcontainer you can continue with Section 3. When you're done with a step, commit your changes. Any time you can re-start by running the command(s) from the README.
cp AGENTS.md.example AGENTS.md, fill in project name and description.
