+
+## Usage
+
+This example uses the whisper.xcframework which needs to be built first using the following command:
+```bash
+./build-xcframework.sh
+```
+
+A model is also required to be downloaded and can be done using the following command:
+```bash
+./models/download-ggml-model.sh base.en
+```
+
+If you don't want to convert a Core ML model, you can skip this step by creating dummy model:
+```bash
+mkdir models/ggml-base.en-encoder.mlmodelc
+```
+
+### Core ML support
+1. Follow all the steps in the `Usage` section, including adding the ggml model file.  
+The ggml model file is required as the Core ML model is only used for the encoder. The
+decoder which is in the ggml model is still required.
+2. Follow the [`Core ML support` section of readme](../../README.md#core-ml-support) to convert the
+model.
+3. Add the Core ML model (`models/ggml-base.en-encoder.mlmodelc/`) to `whisper.swiftui.demo/Resources/models` **via Xcode**.
+
+When the example starts running you should now see that it is using the Core ML model:
+```console
+whisper_init_state: loading Core ML model from '/Library/Developer/CoreSimulator/Devices/25E8C27D-0253-4281-AF17-C3F2A4D1D8F4/data/Containers/Bundle/Application/3ADA7D59-7B9C-43B4-A7E1-A87183FC546A/whisper.swiftui.app/models/ggml-base.en-encoder.mlmodelc'
+whisper_init_state: first run on a device may take a while ...
+whisper_init_state: Core ML model loaded
