+Async Atlan Client (AIO)
+========================
+
+This module provides async versions of all Atlan client functionality
+with the same API as the sync versions, just requiring await.
+
+Pattern: All async methods reuse shared business logic from pyatlan.client.shared
+to ensure identical behavior with sync clients.
+
+Usage:
+    from pyatlan.client.aio import AsyncAtlanClient
+
+    async with AsyncAtlanClient() as client:
+        results = await client.asset.search(criteria)
+
+        # Async iteration through paginated results
+        async for asset in results:
+            print(asset.name)
