 ## Converting to JSON Schema
 
-You can convert any schema to a JSON Schema array or JSON string:
-
-```php
-// Convert to array
-$jsonSchemaArray = $schema->toArray();
-
-// Convert to JSON string
-$jsonSchemaString = $schema->toJson();
-$jsonSchemaString = $schema->toJson(JSON_PRETTY_PRINT);
-```
-
-This will output a valid JSON Schema that can be used with any JSON Schema validator.
+TODO
 
-Example JSON output:
-```json
-{
-    "$schema": "http://json-schema.org/draft-07/schema#",
-    "type": "object",
-    "title": "user",
-    "description": "User schema",
-    "required": ["name", "email"],
-    "properties": {
-        "name": {
-            "type": "string",
-            "minLength": 2,
-            "maxLength": 100
-        },
-        "email": {
-            "type": "string",
-            "format": "email"
-        }
