See [Website development basics](https://docs.kentico.com/documentation/developers-and-admins/development/website-development-basics.md) to learn more about the system's architecture. The following diagram illustrates the most important NuGet packages and their roles: ![Xperience by Kentico NuGet packages](https://docs.kentico.com/docsassets/documentation/xperience-by-kentico-nuget-packages/nugetpackages.png "Xperience by Kentico NuGet packages") | Package | Description | | ----------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [Kentico.Xperience.Templates](https://www.nuget.org/packages/Kentico.Xperience.Templates/) | Provides a set of .NET project templates used to bootstrap new Xperience projects. | | [Kentico.Xperience.DbManager](https://www.nuget.org/packages/Kentico.Xperience.DbManager/) | Provides tooling to install and maintain project databases. | | [Kentico.Xperience.Admin](https://www.nuget.org/packages/Kentico.Xperience.Admin) | Contains the administration interface used to manage Xperience applications. | | [Kentico.Xperience.WebApp](https://www.nuget.org/packages/Kentico.Xperience.WebApp) | Required to run Xperience in ASP.NET Core applications. The package also contains Xperience features and API intended for use within web applications:

This package is required to upload, process, and correctly display images in Xperience as [media library files](https://docs.kentico.com/documentation/business-users/media-libraries/manage-media-files.md). Do not remove the package if you use media libraries unless you provide a custom implementation of `IImageProcessingService`.
The package doesn't guarantee compatibility with niche distributions and platforms. If you run into issues with image processing on the hosting platform of your choice, you will need your own `IImageProcessingService` implementation. | ## Extension packages In addition to the main Xperience NuGet packages, you can install optional extension packages that introduce specific functionality to Xperience and its API: | Package | Description | | ------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [Kentico.Xperience.Cloud](https://www.nuget.org/packages/Kentico.Xperience.Cloud) | Contains:
