+Configuring with YAML Files
+----------------------------
 
+You can configure various options of ``trtllm-serve`` using YAML files by setting the ``--extra_llm_api_options`` option to the path of a YAML file, the arguments in the file will override the corresponding command line arguments.
+
+The yaml file is configuration of `tensorrt_llm.llmapi.LlmArgs <https://nvidia.github.io/TensorRT-LLM/llm-api/reference.html#tensorrt_llm.llmapi.TorchLlmArgs>`_, the class has multiple levels of hierarchy, to configure the top level arguments like ``max_batch_size``, the yaml file should be like:
+
+.. code-block:: yaml
+
+   max_batch_size: 8
+
+To configure the nested level arguments like ``moe_config.backend``, the yaml file should be like:
+
+.. code-block:: yaml
+
+   moe_config:
+       backend: CUTLASS
