# Day 0 — Claude Code Setup
|
|
|
|
This guide walks you through installing Claude Code on your machine and authenticating so you can start using it.
|
|
|
|
## Step 1: Install Claude Code
|
|
|
|
Choose your operating system:
|
|
|
|
| OS | Guide |
|
|
|----|-------|
|
|
| Windows | [windows.md](windows.md) |
|
|
| Linux | [linux.md](linux.md) |
|
|
| macOS | [mac.md](mac.md) |
|
|
|
|
Follow the guide for your OS, then come back here for authentication.
|
|

|
|
## Step 2: Verify Installation
|
|
|
|
After following your OS-specific guide, confirm everything is working:
|
|
|
|
```bash
|
|
node --version # Should show v18.x or higher
|
|
claude --version # Should show the installed Claude Code version
|
|
```
|
|
|
|

|
|
|
|
## Step 3: Login

Run `claude` in your terminal. On first launch, it will ask you to choose a login method.
|
|
|
|
### Method 1: Subscription (Claude Pro / Max)
|
|
|
|
- Select **Claude.ai account**
|
|
- Browser opens — sign in and authorize
|
|
- Return to terminal, you're logged in
|
|
|
|
### Method 2a: API Key (Team Invite)
|
|
|
|
Your team admin invites you from the Anthropic dashboard.
|
|
|
|
- You receive an **invite email** — accept it and create your Anthropic account
|
|
- Run `claude` in your terminal
|
|
- Select **Anthropic API Key**
|
|
- Your key is **auto-generated** on the dashboard — no manual setup needed
|
|
- Claude Code starts working immediately
|
|
|
|
### Method 2b: API Key (You have the key)
|
|
|
|
If someone shared the key with you (via Slack, email, etc.) or you created your own:
|
|
|
|
- Run `claude` in your terminal
|
|
- Select **Anthropic API Key**
|
|
- Paste your key (starts with `sk-ant-`)
|
|
- The key is **stored permanently** — you won't be asked again
