Install Claude Code and download your starter system. This takes about 20 minutes.
If you completed the pre-sprint setup, you can skip this section. This is a reference for anyone who needs help getting Claude Code installed.
Quick setup checklist
npm install -g @anthropic-ai/claude-codeclaude and press EnterThe terminal is just a text-based way to talk to your computer. Instead of clicking through menus, you type commands. That blank screen with the blinking cursor is normal.
Claude Code uses the terminal because from here, it can read your files, create new ones, organize your folders, and actually do things on your computer. You do not need to memorize commands. You just talk.
You will not break anything. The commands we use in this course are simple and safe. If something ever goes wrong, Claude Code itself can help you fix it.
Detailed installation steps
Claude Code is installed. Now you need your starter system. This is a folder with everything already set up for you: your root file template, your memory system folders, your skills, your protocols. You download it once and build on it for the rest of the course.
Your starter system lives on GitHub. GitHub is just a website that stores files, like Google Drive for projects. You do not need to understand how it works. You just need to download one folder from it.
Open Claude Code in your project folder
This is the most important step. Claude Code needs to be opened inside your project folder. This is how it finds your root file and all your system files. If you open Claude Code from the wrong folder, it will not know who you are.
First time logging in
The first time you type claude, it will ask you to log in to your Anthropic account. This is the Claude Pro account you signed up for. Follow the instructions on screen. It will open a browser window, you log in, and come back to the terminal. This only happens once.
After you log in, Claude Code will read your root file (CLAUDE.md) automatically. You will see it reference "The Four Languages Root System" in its startup. That means it found your project. You are in.
Every time you start a session
From now on, every time you want to work with your root system: open your terminal, type cd ~/my-business, then type claude. Two commands. That is your daily start.
What are skills?
Your starter system comes with 40 skills. Skills are instructions that tell Claude how to do a specific task. They live in a hidden folder inside your project called .claude/commands/.
You do not need to read or edit skill files. You just type a skill name and Claude follows the instructions. For example:
That / before the name is how Claude knows you are running a skill, not just typing a word. You will learn specific skills throughout the course. For now, just know: if the course says "type /something", it is a skill, and Claude knows what to do.
Understanding your files
You do not need to learn markdown. Claude writes it for you. You just tell it what you want, in plain language, by typing or speaking. Claude handles the formatting.
Here is what a markdown file looks like, so you can recognize one when you see it:
The # creates a heading. The - creates a bullet point. You do not need to remember any of this. Claude writes it all.
