+# Register Plugin
+
+Provides user registration functionality.
+
+## API Endpoints
+
+### POST /register?action=register
+Register a new user account.
+
+**Request:**
+- `username` (string, 3-20 chars, required)
+- `password` (string, 8-255 chars, required)
+- `confirm_password` (string, required)
+- `csrf_token` (string, required)
+- `terms` (boolean, required)
+
+**Response:**
+```json
+{
+    "success": true,
+    "data": {
+        "message": "Registration successful. You can log in now.",
+        "redirect_to": "?page=login"
+    }
+}
+```
+
+### GET /register?action=status
+Check if registration is enabled.
+
+## Configuration
+
+Enable/disable registration in `totalmeet.conf.php`:
+```php
+'registration_enabled' => true,
+```
+
+## Security Features
+
+- CSRF protection
+- Rate limiting
+- Password hashing
+- Input sanitization
+
+## Implementation
+
+Uses simple callable dispatcher pattern for single-action plugin:
+```php
+register_plugin_route_prefix('register', [
+    'dispatcher' => function($context) {
+        require_once PLUGIN_REGISTER_PATH . 'controllers/register.php';
+    },
+    'access' => 'public',
+]);
+```
+
+## Dependencies
+
+None - functions independently.
