+# JSON schema object wrapper
+
+This module allows wrapping Kotlin objects (e.g. Map, List, primitives) to `AbstractElement` that can be validated by JSON schema.
+
+## Usage
+
+```kotlin
+val schema = JsonSchema.fromDefinition(/*schema*/)
+
+val obj = mapOf(
+  "a" to 42,
+  "b" to listOf("test"),
+  "c" to mapOf(
+    "inner" to 42,
+  ),
+)
+
+val result = schema.validate(wrapAsElement(obj), OutputCollector.flag())
+```
