 ## Dataset Description
 BenchMAX_Multiple_Functions is a dataset of BenchMAX, sourcing from [Nexus](https://huggingface.co/datasets/Nexusflow/NexusRaven_API_evaluation).
+This dataset evaluates the tool use capability, which requires a model to call the correct function given multiple functions.
 
 We translate the standardized queries from English to 16 non-English languages by google Translate.
 Some special function arguments remain English since the APIs are in English.
 All samples are post-edited by native speakers.
 
+## Usage
