 ## Getting ONNX models
 
-* Choose a pre-trained ONNX model from the [ONNX Model Zoo](https://github.com/onnx/models). Many pre-trained ONNX models are provided for common scenarios.
-* Use services like [Azure Custom Vision service](https://docs.microsoft.com/en-us/azure/cognitive-services/Custom-Vision-Service/custom-vision-onnx-windows-ml) that generate customized ONNX models for your data
+* Pre-trained models: Many pre-trained ONNX models are provided for common scenarios in the [ONNX Model Zoo](https://github.com/onnx/models). 
+* Services: Customized ONNX models are generated for your data by cloud based services (see below)
 * Convert models from various frameworks (see below)
