+#### How to find the corresponding deployment config of a PyTorch model
+
+1. Find model's codebase folder in `configs/ `. Example, convert a yolov3 model you need to find `configs/mmdet` folder.
+2. Find model's task folder in `configs/codebase_folder/ `. Just like yolov3 model, you need to find `configs/mmdet/single-stage` folder.
+3. Find deployment config file in `configs/codebase_folder/task_folder/ `. Just like deploy yolov3 model you can use `configs/mmdet/single-stage/single-stage_onnxruntime_dynamic.py`.

-### 5. How to write model config
+### 5. The name rules of our deployment config
+
+There is a specific naming convention for the filename of deployment config files.
+
+```bash
+(task name)_(partition)_(backend name)_(dynamic or static).py
+```
+
+- `task name`: Model's task type.
+- `partition`: Optional, whether partition model is supported.
+- `backend name`: Backend's name. Note if you use the quantization function, you need to indicate the quantization type. Just like `tensorrt_int8`.
+- `dynamic or static`: Dynamic or static export. Note if the backend needs explicit shape information, you need to add a description of input size with `height x width` format. Just like `dynamic-512x1024-2048x2048`, it means that the min input shape is `512x1024` and the max input shape is `2048x2048`.
+
+#### Example
+
+```
+single-stage_partition_tensorrt-int8_dynamic-320x320-1344x1344.py
+```
+
+### 6. How to write model config
 
 According to model's codebase, write the model config file. Model's config file is used to initialize the model, referring to [MMClassification](https://github.com/open-mmlab/mmclassification/blob/master/docs/tutorials/config.md), [MMDetection](https://github.com/open-mmlab/mmdetection/blob/master/docs_zh-CN/tutorials/config.md), [MMSegmentation](https://github.com/open-mmlab/mmsegmentation/blob/master/docs_zh-CN/tutorials/config.md), [MMOCR](https://github.com/open-mmlab/mmocr/tree/main/configs), [MMEditing](https://github.com/open-mmlab/mmediting/blob/master/docs_zh-CN/config.md).
