+## About NVIDIA NIM Image OCR
+
+The [NVIDIA NIM for Image OCR API](https://docs.nvidia.com/nim/ingestion/table-extraction/latest/overview.html) is an (Optical Character Recognition) microservice and interface that extracts text from images on NVIDIA NIM.
+
+

+## Supported models
+
+### NVIDIA NIM for Image OCR
+
+* [baidu/paddleocr](https://build.nvidia.com/baidu/paddleocr/modelcard) (default)
+
+
+## Creating the default model
+
+```sql
+SELECT aidb.create_model(
+    'my_paddle_ocr_model',
+    'nim_paddle_ocr',
+    credentials => '{"api_key": "__NVIDIA_NIM_API_KEY__" }'::JSONB
+);
+```
+
+There is currently only one model supported by [NVIDIA NIM for Image OCR API](https://docs.nvidia.com/nim/ingestion/table-extraction/latest/support-matrix.html), the default `baidu/paddleocr`, so you don't need to specify the model in the configuration.
