 1. **Model Source**: You should provide the source file for the model (.py format).
 
-    Place the source file under `onnx\models\toolchain\models` and place the onnx file under the appropriate task category in the repo root. All pretrained models should include valid weights.
+    Place the source file under [turnkeyml/models](https://github.com/onnx/turnkeyml/tree/main/models) and place the onnx file under the appropriate task category in the [onnx model zoo repo root](https://github.com/onnx/models). All pretrained models should include valid weights.
 
     The source file must include the following labels at the top of the file:
 
         - Author - Name of the organization or the creator of the model
         - Task - For example, Computer Vision, Natural Language Processing (NLP), Audio Processing, MultiModal, Generative AI ,Graph Machine Learning ...
         - License: Submissions should be under one of the following licenses: Apache-2.0, BSD-3, or MIT.
