+## YugabyteDBChatStore
+
+Using `YugabyteDBChatStore`, you can store your chat history remotely, without having to worry about manually persisting and loading the chat history.
+
+### Prerequisites
+
+Before using this integration, you'll need to have a YugabyteDB instance running. You can set up a local YugabyteDB instance by following the [YugaByteDB Quick Start Guide](https://docs.yugabyte.com/preview/quick-start/macos/).
+
+### Installation
+
+```shell
+pip install llama-index-storage-chat-store-yugabytedb
+```
+
+### Usage
+
+```python
+from llama_index.storage.chat_store.yugabytedb import YugabyteDBChatStore
+from llama_index.core.memory import ChatMemoryBuffer
+
+chat_store = YugabyteDBChatStore.from_uri(
+    uri="yugabytedb+psycopg2://yugabyte:[email protected]:5433/yugabyte?load_balance=true",
+)
+
+chat_memory = ChatMemoryBuffer.from_defaults(
+    token_limit=3000,
+    chat_store=chat_store,
+    chat_store_key="user1",
+)
+```
+
+#### Connection String Parameters
