# Feature Impact

> Leverage this guide on using Fiddler's feature impact upload API to supply your own feature impact values for your Fiddler model.

This guide will walk you through the steps needed to upload your model's existing feature impact values to your Fiddler model. This notebook uses the same example model leveraged in the [ML Monitoring - Simple](/developers/quick-starts/simple-ml-monitoring) quick start. If you have already run that notebook and the model exists in your Fiddler instance, then you may skip the setup steps in this guide as noted in the instructions.
