-- Clients can have a replica of the document representing an application model locally on several devices.
-- Each client can independently update the document on their local device, even while offline.
-- When a network connection is available, the client figures out which changes need to be synced from one device to another, and brings them into the same state.
-- If the document was changed concurrently on different devices, Yorkie automatically syncs the changes, so that every replica ends up in the same state with resolving conflict.
+Key Features:
+
+- Clients: Clients can have a local replica of the document representing an application model on several devices.
+- Offline Editing: Each client can independently update the document on their local device, even while offline.
+- Synchronization: When a network connection is available, the client figures out which changes need to be synced from one device to another, and brings them into the same state.
+- Conflict Resolution: If the document was changed concurrently on different devices, Yorkie automatically syncs the changes, so that every replica ends up in the same state with resolving conflicts.
+- Database Integration: Yorkie supports MongoDB and MemDB as the underlying data storage.
