# Example Project

The PSPDFKit.NET Library comes with an example application called the Catalog app, which contains many useful examples for exploring the different features of PSPDFKit and getting started quickly. You can find the app in the `Example` folder of the SDK ZIP file. The SDK ZIP file can be downloaded from the [PSPDFKit Portal](https://my.pspdfkit.com) or by [requesting an evaluation license](https://www.nutrient.io/try) of PSPDFKit.
