Day 13 / 100 · Setup

One project. One folder.

Everything for a project lives in one folder. Start Claude Code inside it, and that folder is what it works on.

A Typical Project

my-leave-form/
├─ index.html the page
├─ style.css how it looks
├─ script.js what it does
├─ README.md how to run it
├─ CLAUDE.md rules for the agent
├─ .gitignore what Git must skip
└─ .env secrets, never shared

Folder rules

One folder per project. Never mix two.

No spaces in names: my-leave-form, not My Leave Form.

Keep projects in one home, like Documents/projects, not Downloads or the Desktop.

cd into the folder before you type claude.

Where you start Claude is what it works on. Choose on purpose.
