 ## Apple Silicon detector
 
 The NPU in Apple Silicon can't be accessed from within a container, so the [Apple Silicon detector client](https://github.com/frigate-nvr/apple-silicon-detector) must first be setup. It is recommended to use the Frigate docker image with `-standard-arm64` suffix, for example `ghcr.io/blakeblackshear/frigate:stable-standard-arm64`.

 ## CPU Detector (not recommended)
 
 The CPU detector type runs a TensorFlow Lite model utilizing the CPU without hardware acceleration. It is recommended to use a hardware accelerated detector type instead for better performance. To configure a CPU based detector, set the `"type"` attribute to `"cpu"`.

 ### Downloading NanoDet-Plus models
+NanoDet-Plus can be downloaded using the command below. Copy and paste the complete command to your terminal to export
+the model as `nanodet_plus.onnx` in the current working directory. The command builds the NanoDet-Plus environment,
+downloads the specified model and converts it to ONNX.
+
+The below command is configured to use the smallest model provided by the authors, NanoDet-Plus-m-320. Other models
+can be specified by changing the `URL_WEIGHTS` link to the appropriate pretrained weights URL from
+[NanoDet-Plus Model Zoo](https://github.com/RangiLyu/nanodet#model-zoo). Remember to change the `IMG_HEIGHT`,
+`IMG_WIDTH` and `CFG_PATH` ([configuration files](https://github.com/RangiLyu/nanodet/tree/main/config)) parameters
+accordingly.
