📚 DOCS: Update README for v0.1.0 API changes

- Remove all outdated API examples (sendEmail, scheduleEmail)
- Add comprehensive examples using new payload.create() approach
- Include template engine configuration options (LiquidJS, Mustache, custom)
- Add detailed migration guide from v0.0.x to v0.1.0
- Update feature list to highlight type safety and Payload integration
- Replace old API methods section with helper functions

 📧 **Template-based email system with scheduling and job processing for PayloadCMS**
 
-⚠️ **Pre-release Warning**: This package is currently in active development (v0.0.x). Breaking changes may occur before v1.0.0. Not recommended for production use.
+✨ **Simplified API**: Starting from v0.1.0, this plugin uses a simplified API that leverages PayloadCMS collections directly for better type safety and flexibility.
 
 ## Features
 
-✅ **Template System**: Create reusable email templates with Handlebars syntax  
+✅ **Template System**: Create reusable email templates with LiquidJS, Mustache, or simple variables
-✅ **Outbox Scheduling**: Schedule emails for future delivery  
+✅ **Type Safety**: Full TypeScript support using your generated Payload types
+✅ **Flexible Template Engines**: LiquidJS, Mustache, or bring your own template renderer
+✅ **Email Scheduling**: Schedule emails for future delivery using Payload collections
 ✅ **Job Integration**: Automatic processing via PayloadCMS jobs queue
 ✅ **Retry Failed Sends**: Automatic retry mechanism for failed emails
-✅ **Template Variables**: Dynamic content with validation  
+✅ **Payload Native**: Uses Payload collections directly - no custom APIs to learn
-✅ **Developer API**: Simple methods for sending emails programmatically

-import { sendEmail, scheduleEmail } from '@xtr-dev/payload-mailing'
+import { renderTemplate } from '@xtr-dev/payload-mailing'
 
-// Send immediately using template slug
+// Option 1: Using templates with variables

 })
 ```
 
+## Why This Approach is Better
+
+- ✅ **Full Type Safety**: Use your generated Payload types
+- ✅ **No Learning Curve**: Just use `payload.create()` like any collection
+- ✅ **Maximum Flexibility**: Add any custom fields to your email collection
+- ✅ **Payload Integration**: Leverage validation, hooks, access control
+- ✅ **Consistent API**: One way to create data in Payload

-## Handlebars Helpers
+## Template Syntax Reference
 
-The plugin includes several built-in helpers:
+Depending on your chosen template engine, you can use different syntax:
 
-- `{{formatDate date 'short'}}` - Format dates (short, long, or default)
+### LiquidJS (Default)
-- `{{formatCurrency amount 'USD'}}` - Format currency
+- Variables: `{{ user.name }}`
-- `{{capitalize string}}` - Capitalize first letter
+- Logic: `{% if user.isPremium %}Premium content{% endif %}`
-- `{{#ifEquals value1 value2}}...{{/ifEquals}}` - Conditional equality
+- Loops: `{% for item in items %}{{ item.name }}{% endfor %}`
+- Filters: `{{ amount | formatCurrency }}`, `{{ date | formatDate: "short" }}`
 
-## API Methods
+### Mustache
+- Variables: `{{ user.name }}`
+- Logic: `{{#user.isPremium}}Premium content{{/user.isPremium}}`
+- Loops: `{{#items}}{{ name }}{{/items}}`
+- No built-in filters (use variables with pre-formatted data)
 
-### sendEmail(payload, options)
+### Simple
+- Variables only: `{{ user.name }}`, `{{ amount }}`, `{{ date }}`
 
-Send an email immediately:
+### Built-in Filters (LiquidJS only)
+- `formatDate` - Format dates: `{{ createdAt | formatDate: "short" }}`

+## Migration Guide (v0.0.x → v0.1.0)
+
+**🚨 BREAKING CHANGES**: The API has been simplified to use Payload collections directly.
+
+### Before (v0.0.x)
+```typescript
+import { sendEmail, scheduleEmail } from '@xtr-dev/payload-mailing'
+
+// Old way
+const emailId = await sendEmail(payload, {
+  templateSlug: 'welcome',
+  to: 'user@example.com',
+  variables: { name: 'John' }
+})
+
+const scheduledId = await scheduleEmail(payload, {
+  templateSlug: 'reminder',
+  to: 'user@example.com',
+  scheduledAt: new Date('2024-01-15T10:00:00Z'),
+  variables: { eventName: 'Launch' }
+})
+```
+
+### After (v0.1.0+)
+```typescript
+import { renderTemplate } from '@xtr-dev/payload-mailing'
+
+// New way - render template first
+const { html, text, subject } = await renderTemplate(payload, 'welcome', {
+  name: 'John'
+})
+
+// Then create email using Payload collections (full type safety!)
+const email = await payload.create({
+  collection: 'emails',
+  data: {
+    to: ['user@example.com'],
+    subject,
+    html,
+    text,
+    // For scheduling
+    scheduledAt: new Date('2024-01-15T10:00:00Z'),
+    // Add any custom fields from your collection
+    customField: 'value',
+  }
+})
+```
+
+### Benefits of Migration
+- ✅ **Full TypeScript support** with your generated Payload types
+- ✅ **Use any custom fields** you add to your email collection
+- ✅ **Leverage Payload's features**: validation, hooks, access control
+- ✅ **One consistent API** - just use `payload.create()`
+- ✅ **No wrapper methods** - direct access to Payload's power
