-  If the model you are using does not match the default prompt provided in this repository and cannot achieve the best results, we support adding custom prompts. The prompts in the repository are divided into three parts:
-  - `prompt`: Mainly used to guide the model on how to process and convert text content in images.
-  - `rect_prompt`: Used to handle cases where specific areas (such as tables or images) are marked in the image.
-  - `role_prompt`: Defines the role of the model to ensure the model understands it is performing a PDF document parsing task.

+  Custom area-specific prompts for handling marked regions (tables/images).
+
+- **role_prompt**: *str*, default: Use built-in prompts  
+  Custom role definition prompt to ensure model understands its parsing task.
 
   You can pass custom prompts in the form of a dictionary to replace any of the prompts. Here is an example:
 
 ```
-prompt = {
-    "prompt": "Custom prompt text",
-    "rect_prompt": "Custom rect prompt",
-    "role_prompt": "Custom role prompt"
-}
