You've installed AuthCore in **Full Template Mode**! 🎉

## What This Means

Instead of importing components from \`codalware-auth\`, you now have:

- ✅ **Complete source code** in your project
- ✅ **Full customization** - modify any file
- ✅ **No dependency lock-in** - the code is yours
- ✅ **Easy debugging** - all code is visible

## Project Structure

\`\`\`

├── components/authcore/     ← All UI components
│   ├── LoginForm.tsx
│   ├── RegisterForm.tsx
│   ├── AuthForm.tsx
│   └── ... (all other components)

## Usage

### Import Components

\`\`\`typescript
// Instead of:
// import { LoginForm } from 'codalware-auth';

// Use:
import { LoginForm } from '@/components/authcore';
\`\`\`

### Import Hooks

\`\`\`typescript
// Instead of:
// import { useAuth } from 'codalware-auth';

// Use:
import { useAuth } from '@/hooks/authcore';
\`\`\`

### Import Server Utils

\`\`\`typescript
// Instead of:
// import { AuthService } from 'codalware-auth/server';

// Use:
import { AuthService } from '@/lib/auth';
\`\`\`

## Customization

### Modify Components

Want to change the LoginForm design? Just edit:
\`src/components/authcore/LoginForm.tsx\`

### Modify Auth Logic

Want to change registration flow? Edit:
\`src/lib/auth/logic/auth.ts\`

### Modify Validation

Want custom password rules? Edit:
\`src/lib/validation/schemas.ts\`

## Package Dependency

The \`codalware-auth\` package is now **optional**. You can:

1. Keep it for potential updates
2. Remove it completely - your code will still work!

To remove the dependency:
\`\`\`bash
npm uninstall codalware-auth
\`\`\`

## Updates

Since you own the code, updates work differently:

1. Check for new features: \`npx authcore check-updates\`
2. See what changed: \`npx authcore diff\`
3. Manually apply updates you want

Or regenerate specific parts:
\`\`\`bash
npx authcore generate components  # Regenerate components
npx authcore generate hooks       # Regenerate hooks
\`\`\`

## Support

- **Documentation**: https://authcore-liard.vercel.app/
- **Examples**: https://authcore-liard.vercel.app/examples
- **Customization Guide**: https://authcore-liard.vercel.app/guides/customization

**You own this code!** Modify it however you want. Good luck! 🚀

  const content = `# AuthCore Main Template

This project was initialized with AuthCore as the main source code. AuthCore components, hooks, and utilities are now your primary codebase.

## What's Included

- **Components**: All AuthCore UI components in \`src/components/\`
- **Hooks**: Authentication hooks in \`src/hooks/\`
- **Server Utils**: Authentication logic in \`src/lib/auth/\`
- **Validation**: Form validation utilities in \`src/lib/validation/\`
- **Utils**: Helper functions in \`src/lib/utils/\`
- **I18n**: Internationalization in \`src/lib/i18n/\`
- **Types**: TypeScript definitions in \`src/types/\`
- **Styles**: Tailwind preset and CSS in \`styles/\`
- **Locales**: Translation files in \`locales/\`

## Quick Start

\`\`\`tsx
import { LoginForm, RegisterForm } from '@/components';
import { useAuth } from '@/hooks';

export default function App() {
  const { user, login, logout } = useAuth();

  return (
    <div>
      {user ? (
        <div>
          <p>Welcome, {user.email}!</p>
          <button onClick={logout}>Logout</button>
        </div>
      ) : (
        <LoginForm onSubmit={login} />
      )}
    </div>
  );
}
\`\`\`

## Configuration

1. Copy \`.env.example\` to \`.env.local\`
2. Configure your database and email settings
3. Run database migrations: \`npm run migrate\`
4. Start the development server: \`npm run dev\`

## Customization

Since AuthCore is now your main source code, you can:

- Modify any component in \`src/components/\`
- Add new authentication flows in \`src/hooks/\`
- Extend server utilities in \`src/lib/\`
- Update styles in \`styles/\`
- Add new locales in \`locales/\`

## Database Setup

This template includes Prisma schema and migrations. To set up:

\`\`\`bash
# Install dependencies
npm install

# Set up database
npm run setup-db

# Run migrations
npm run migrate

# Seed database (optional)
npm run seed
\`\`\`

## API Routes

AuthCore provides the following API routes:

- \`POST /api/auth/login\` - User login
- \`POST /api/auth/register\` - User registration
- \`POST /api/auth/logout\` - User logout
- \`GET /api/auth/session\` - Get current session
- \`POST /api/auth/forgot-password\` - Request password reset
- \`POST /api/auth/reset-password\` - Reset password

## Next Steps

1. Review and customize the components in \`src/components/\`
2. Configure your authentication providers in \`src/lib/auth/\`
3. Set up your database connection in \`.env.local\`
4. Test the authentication flows
5. Deploy your application
