+```
+
+## 🚀 Getting Started
+
+### Prerequisites
+
+- Node.js 20+
+- npm installed
+- Playwright browsers installed
+
+### Installation
+
+Playwright is already installed in this project. If you need to reinstall browsers:
+
+```bash
+npx playwright install
+```
+
+## 🎯 Running Tests
+
+### Run all tests (headless)
+```bash
+npm run test:e2e
+```
+
+### Run tests with UI (interactive mode)
+```bash
+npm run test:e2e:ui
+```
+
+### Run tests in headed mode (see browser)
+```bash
+npm run test:e2e:headed
+```
+
+### Run tests in debug mode (step through tests)
+```bash
+npm run test:e2e:debug
+```
+
+### Run specific test file
+```bash
+npx playwright test tests/auth/login.spec.ts
+```
+
+### Run tests matching a pattern
+```bash
+npx playwright test --grep "login"
+```
+
+### View test report
+```bash
+npm run test:e2e:report
+```
+
+## 🎬 Recording Tests (Codegen)
+
+Playwright has a built-in test generator that records your actions:
+
+```bash
+npm run test:e2e:codegen
+```
+
+This opens a browser where you can interact with your app. Playwright will generate test code for your actions.
+
+## 🔐 Authentication
+
+Tests use a global authentication setup to avoid logging in before every test.
+
+### How it works:
+1. `auth.setup.ts` runs once before all tests
+2. Logs in with test credentials
+3. Saves authentication state to `tests/.auth/user.json`
+4. Other tests reuse this state
+
+### Test Credentials
+
+Set these environment variables (or use defaults):
+
+```bash
+export TEST_USER_EMAIL="test@bakery.com"
+export TEST_USER_PASSWORD="test-password-123"
+```
+
+### Creating authenticated tests
+
+```typescript
+import { test, expect } from '@playwright/test';
+
+test.describe('My Test Suite', () => {
+  // Use saved auth state
+  test.use({ storageState: 'tests/.auth/user.json' });
+
+  test('my test', async ({ page }) => {
+    // Already logged in!
+    await page.goto('/app/dashboard');
+  });
+});
+```
+
+## 📝 Writing Tests
+
+### Basic Test Structure
+
+```typescript
+import { test, expect } from '@playwright/test';
+
+test.describe('Feature Name', () => {
+  test.beforeEach(async ({ page }) => {
+    // Setup before each test
+    await page.goto('/your-page');
+  });
+
+  test('should do something', async ({ page }) => {
+    // Your test code
+    await page.getByRole('button', { name: 'Click me' }).click();
+    await expect(page).toHaveURL('/expected-url');
+  });
+});
+```
+
+### Using Helpers
+
+```typescript
+import { login, logout, TEST_USER } from '../helpers/auth';
+import { waitForLoadingToFinish, expectToastMessage } from '../helpers/utils';
+
+test('my test with helpers', async ({ page }) => {
+  await login(page, TEST_USER);
+  await waitForLoadingToFinish(page);
+  await expectToastMessage(page, 'Success!');
+});
+```
+
+### Best Practices
+
+1. **Use semantic selectors**
+   ```typescript
+   // ✅ Good
+   page.getByRole('button', { name: 'Submit' })
+   page.getByLabel('Email')
+
+   // ❌ Avoid
+   page.locator('.btn-primary')
+   page.locator('#email-input')
+   ```
+
+2. **Wait for elements properly**
+   ```typescript
+   // ✅ Good - Auto-waits
+   await page.getByText('Hello').click();
+
+   // ❌ Avoid - Manual waits
+   await page.waitForTimeout(3000);
+   ```
+
+3. **Use data-testid for complex elements**
+   ```typescript
+   // In your component
+   <div data-testid="product-card">...</div>
+
+   // In your test
+   await page.getByTestId('product-card').click();
+   ```
+
+4. **Reuse authentication**
+   ```typescript
+   // ✅ Good - Reuse saved state
+   test.use({ storageState: 'tests/.auth/user.json' });
+
+   // ❌ Avoid - Login in every test
+   test.beforeEach(async ({ page }) => {
+     await login(page);
+   });
+   ```
+
+## 🔍 Debugging Tests
+
+### 1. Use Playwright Inspector
+```bash
+npm run test:e2e:debug
+```
+
+### 2. Use console.log
+```typescript
+test('debug test', async ({ page }) => {
+  console.log('Current URL:', page.url());
+});
+```
+
+### 3. Take screenshots
+```typescript
+await page.screenshot({ path: 'screenshot.png' });
+```
+
+### 4. View trace
+When tests fail, check the trace viewer:
+```bash
+npx playwright show-trace test-results/trace.zip
+```
+
+## 🎨 Test Reports
+
+After running tests, view the HTML report:
+
+```bash
+npm run test:e2e:report
+```
+
+This shows:
+- ✅ Passed tests
+- ❌ Failed tests
+- 📸 Screenshots on failure
+- 🎥 Videos on failure
+- 📊 Traces for debugging
+
+## 🌐 Multi-Browser Testing
+
+Tests run on multiple browsers automatically:
+- Chromium (Chrome/Edge)
+- Firefox
+- WebKit (Safari)
+- Mobile Chrome
+- Mobile Safari
+
+Configure in `playwright.config.ts`.
+
+## 📱 Mobile Testing
+
+Tests automatically run on mobile viewports. To test specific viewport:
+
+```typescript
+test('mobile test', async ({ page }) => {
+  await page.setViewportSize({ width: 375, height: 667 });
+  // Your test
+});
+```
+
+## 🔄 CI/CD Integration
+
+Tests run automatically on GitHub Actions:
+
+- ✅ On every push to `main` or `develop`
+- ✅ On every pull request
+- ✅ Uploads test reports as artifacts
+- ✅ Comments on PRs with results
+
+### GitHub Secrets Required
+
+Set these in your repository settings:
+- `TEST_USER_EMAIL`: Test user email
+- `TEST_USER_PASSWORD`: Test user password
+
+## 🧪 Test Coverage
+
+Current test coverage:
+
+- ✅ Authentication (login, register, logout)
+- ✅ Onboarding wizard
+- ✅ Dashboard smoke tests
+- ✅ Purchase order management
+- ✅ Product/Recipe creation
+- 🔜 Analytics pages
+- 🔜 Settings pages
+- 🔜 Team management
+- 🔜 Payment flows
+
+## 🚨 Common Issues
+
+### Tests fail with "timeout exceeded"
+- Check if dev server is running
+- Increase timeout in `playwright.config.ts`
+- Check network speed
+
+### Authentication fails
+- Verify test credentials are correct
+- Check if test user exists in database
+- Clear `.auth/user.json` and re-run
+
+### "Element not found"
+- Check if selectors match your UI
+- Add `await page.pause()` to inspect
+- Use Playwright Inspector
+
+### Tests work locally but fail in CI
+- Check environment variables
+- Ensure database is seeded with test data
+- Check for timing issues (add explicit waits)
+

+- [API Reference](https://playwright.dev/docs/api/class-playwright)

+
+## 🤝 Contributing
+
+When adding new features:
+
+1. Write E2E tests for critical user flows
+2. Use existing helpers and utilities
+3. Follow the established test structure
+4. Add test data to `fixtures/` if needed
+5. Update this README if adding new patterns
+
+## 💡 Tips
+
+- Use `test.only()` to run a single test during development
+- Use `test.skip()` to temporarily disable a test
+- Group related tests with `test.describe()`
+- Use `test.beforeEach()` for common setup
+- Keep tests independent and isolated
+- Name tests descriptively: "should [action] when [condition]"
