-Now that everything is configured to get started, we can walk through, step-by-step, how to build your first analyzer, starting with building the schema. The schema is the customizable framework that allows the analyzer to extract insights from your data. In this example, the schema is created to extract key data from an invoice document, but you can bring in any type of data and the steps remain the same.

+* **Multi-file task:** A multi-file task utilizes Content Understandning Pro mode and allows you to bring in multiple files to create your analyzer. You can also bring in a set of reference data that the service can use to perform multi-step reasoning and make conclusions about your data.
