## Day 1: Getting Started

### Your First Day Checklist

- [ ] Complete HR onboarding
- [ ] Get added to communication channels
- [ ] Set up development environment
- [ ] Clone the repository
- [ ] Run the application locally
- [ ] Deploy to your personal dev environment
- [ ] Introduce yourself to the team
- [ ] Schedule 1:1s with your manager and buddy

### Access & Accounts

**Required Accounts**:
1. **GitHub** - Source code ([github.com/company/project](https://github.com))
   - Request access from @engineering-manager
2. **Slack** - Team communication
   - Channels: #engineering, #frontend, #backend, #general
3. **Jira** - Project management ([company.atlassian.net](https://company.atlassian.net))
4. **Figma** - Design files
5. **AWS Console** - Production access (read-only initially)
6. **DataDog** - Monitoring and logs

**Development Tools**:
- Docker Desktop
- Node.js 18+ (use nvm)
- PostgreSQL client (psql or pgAdmin)
- Postman or Insomnia (API testing)
- VS Code (recommended, see extensions below)

### Environment Setup

#### 1. Install Prerequisites

**macOS**:
```bash
# Install Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Install Node.js via nvm
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
nvm install 18
nvm use 18

# Install Docker Desktop
brew install --cask docker

# Install PostgreSQL client
brew install postgresql@14
```

**Windows**:
```bash
# Install using Chocolatey
choco install nodejs-lts docker-desktop postgresql14
```

#### 2. Clone Repository

```bash
# Clone the repo
git clone [email protected]:company/ecommerce-platform.git
cd ecommerce-platform

# Install dependencies
npm install

# Copy environment variables
cp .env.example .env.local
```

#### 3. Configure Environment Variables

Edit `.env.local`:
```bash
# Database (local Docker)
DATABASE_URL=postgresql://postgres:password@localhost:5432/ecommerce_dev

# Redis
REDIS_URL=redis://localhost:6379

# Stripe (use test keys)
STRIPE_SECRET_KEY=sk_test_... # Get from @backend-lead
STRIPE_PUBLISHABLE_KEY=pk_test_...

# AWS S3 (dev bucket)
AWS_ACCESS_KEY_ID=... # Get from @devops
AWS_SECRET_ACCESS_KEY=...
AWS_S3_BUCKET=ecommerce-dev-uploads

# Session
SESSION_SECRET=your-random-secret-here
```

**Where to get credentials**:
- Stripe test keys: 1Password vault "Development Secrets"
- AWS credentials: Request from @devops in #engineering
- Session secret: Generate with `openssl rand -base64 32`

#### 4. Start Development Environment

```bash
# Start Docker services (PostgreSQL, Redis)
docker-compose up -d

# Run database migrations
npm run db:migrate

# Seed database with sample data
npm run db:seed

# Start development server
npm run dev
```

**Expected output**:
```
✔ Database migrated successfully
✔ Seeded 100 products, 50 users
✔ Server running on http://localhost:3000
✔ API available at http://localhost:3000/api
```

#### 5. Verify Installation

Open your browser to http://localhost:3000

You should see the application home page with sample products.

**Test credentials**:
- Email: `[email protected]`
- Password: `password123`

**Troubleshooting**:
- **Port 3000 in use**: Kill the process with `lsof -ti:3000 | xargs kill -9`
- **Database connection failed**: Check Docker is running with `docker ps`
- **Module not found**: Delete `node_modules` and run `npm install` again

See [Troubleshooting Guide](docs/TROUBLESHOOTING.md) for more help.

1. **Create a branch**:
   ```bash
   git checkout -b test/your-name-setup
   ```

2. **Add your name to the team page**:
   Edit `src/pages/About.tsx`:
   ```typescript
   const teamMembers = [
     // ... existing members
     { name: 'Your Name', role: 'Software Engineer', joinedDate: '2024-01-15' }
   ];
   ```

3. **Test your change**:
   ```bash
   npm run test
   npm run lint
   ```

4. **Commit and push**:
