Claude Code Setup Guide

Here is how to install Claude Code:

1. 1.Go to claude.ai/download and sign into your Anthropic account. If you do not have one yet, create a free account. You will need a subscription to use Claude Code. The Pro plan at $20/month works.
2. 2.Install Node.js if you do not have it. Go to nodejs.org, download the LTS version, and run the installer. Takes 2 minutes. Claude Code requires Node to run.
3. 3.Open your terminal. On Mac, search "Terminal" in Spotlight. On Windows, open WSL. On Linux, you already know where it is.
4. 4.Run: npm install -g @anthropic-ai/claude-code. Let it finish. When you see a success message, Claude Code is installed.
5. 5.Type claude and hit enter. It pops open a browser to connect your Anthropic account. Authorize it. You are in.

Run this to confirm everything is working

What version of Claude Code am I running? And what is my current working directory? If anything looks wrong or I am missing any dependencies, tell me exactly how to fix it.

Here is how to set up GitHub:

1. 1.Go to github.com and create a free account. Pick a username you are fine with publicly.
2. 2.Check if Git is installed. On Mac, run git --version in your terminal. If it says "command not found," run brew install git. Ask Claude Code how to install Homebrew if you need to.
3. 3.Set your git identity. Run: git config --global user.name "Your Name" and git config --global user.email "you@email.com"
4. 4.Set up SSH keys. This lets you push code without typing your password every time. Paste the prompt below and Claude walks you through the whole thing.

Set up GitHub SSH access

Help me connect my GitHub account with SSH so I can push code without typing my password every time. Walk me through generating an SSH key pair, adding the public key to my GitHub account at github.com/settings/keys, and testing the connection. Explain each step before you run it so I know what is happening.

Here is how to set up Supabase:

1. 1.Go to supabase.com and create a free account. Verify your email.
2. 2.Click "New project." Name it after what you are building. Pick a region close to where your users are. Set a strong database password and save it somewhere. You will need it later.
3. 3.Wait about 2 minutes while it spins up. Then go to Settings, then API. You will see your Project URL and your anon/public API key. Keep that tab open. Claude Code needs both when it sets up your project.

Here is how to set up Vercel:

1. 1.Go to vercel.com and create a free account. Sign up with GitHub so they connect from the start.
2. 2.Click "Add New Project." Import your GitHub repo. If you do not have a project yet, do this after you run the first-project prompt below.
3. 3.Vercel detects Next.js automatically. Leave the defaults. Add your environment variables (Supabase URL and anon key) under Environment Variables. Click Deploy.
4. 4.About 60 seconds later you have a live URL. Share it with anyone.

Build your first project

I just set up Claude Code, GitHub with SSH access, a Supabase project, and a Vercel account. I am ready to build my first project. Here is what I want to build: [describe your project in 2-3 sentences].

Before writing any code, help me set up the project structure. Create a new Next.js project with TypeScript and Tailwind CSS. Connect it to my GitHub account by creating a new private repo. Create a CLAUDE.md file that tells you how I want this project built. Then walk me through connecting it to Supabase and deploying it to Vercel. Go step by step and wait for me to confirm each step before moving on.
