Day 4

The Magic of CLAUDE.md

Let's teach Claude about YOU!

Today's Lesson

CLAUDE.md is a briefing document for Claude Code - it tells Claude what to know about your project, your preferences, and how you want to communicate. Every project can have its own CLAUDE.md, and Claude reads it automatically when you start a session.

Today's Tasks

  1. 1Navigate to your `cc30` folder
  2. 2Ask Claude Code to create a CLAUDE.md file
  3. 3Include: what this folder is for, your skill level, how you want Claude to communicate
  4. 4Start a new Claude Code session and see how it uses the context

Prompt to Use

Create a CLAUDE.md file for this project. This is my learning folder for the 100 Days of Claude Code challenge. I'm a beginner with terminal and coding. I prefer explanations with analogies. Include any other context you think would be helpful.

Expected Outcome

A CLAUDE.md file that shapes how Claude Code interacts with you in this folder.

New Terms

  • CLAUDE.md
  • Context
  • Dotfile

Pro Tip

You can have different CLAUDE.md files in different folders. Each project can have its own briefing.

Coming Tomorrow

We'll edit files and learn about Claude Code's safety net - checkpoints.

P.S. This file is like training an assistant. The better the brief, the better the help.
