# Enriching Raw Data

The 'Enrich' step will be the first one you add to your build flow after setting up your model's inputs.

It will allow you to apply some simple transformation to data inputs and to enrich them with data from other sources, ensuring you get the variables you need, in the correct format, that you'll then use later in your model.
