+# LlamaIndex Chat_Store Integration: YugabyteDB Chat Store
+
+## 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
+
+Using `YugabyteDBChatStore`, you can store your chat history remotely, without having to worry about manually persisting and loading the chat history.
+
+```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
+
+The connection string passed to `YugabyteDBChatStore.from_uri()` supports various parameters that can be used to configure the connection to your YugabyteDB cluster.
+You can find a complete list of supported parameters in the [YugabyteDB psycopg2 Driver Documentation](https://docs.yugabyte.com/preview/drivers-orms/python/yugabyte-psycopg2/#step-2-set-up-the-database-connection).
+
+The YugabyteDB specific parameters include:
+
+- `load_balance`: Enable/disable load balancing (default: false)
+- `topology_keys`: Specify preferred nodes for connection routing
+- `yb_servers_refresh_interval`: Interval (in seconds) to refresh the list of available servers
+- `fallback_to_topology_keys_only`: Whether to only connect to nodes specified in topology_keys
+- `failed_host_ttl_seconds`: Time (in seconds) to wait before trying to connect to failed nodes
