 > Same as `GeminiClient.generate_content`, `ChatSession.send_message` also accepts `image` as an optional argument.
 
+### Continue past conversations
+
+To retrive past conversations you can pass through the `cid`, `rid` and `rcid` through the `metadata` argument in the `start_chat()` function. To Alternitavly if you want to save the variables you can get it from `chat_session.metadata`. 
+
+```python
+async def main():
+    # Load the past conversation
+    chat = client.start_chat("Your chat id")
+    responce = await chat.send_message("What was my previous message?")
+    # Save the conversation id
+    gemini_chatID = chat.metadata   
+```
+
+> [!IMPORTANT]
+>
+> Storing the chat variables in a local variable like in this example will get eraced at runtime.
+> If you would like to save these it is recomended to store it in json or in a database of some short.

 ### Retrieve images in response
 
 Images in the API's output are stored as a list of `Image` objects. You can access the image title, URL, and description by calling `image.title`, `image.url` and `image.alt` respectively.
