Kentico provides integration ([NuGet](https://www.nuget.org)) packages that help with the development of MVC websites. You can integrate the following types of NuGet packages into your project:

- [MVC integration package](#kentico.web.mvc-integration-package)
- [Kentico.Libraries integration package](#kentico.libraries-integration-package)
- [General integration packages](#general-integration-packages)

## Installing Kentico integration packages

1. Visual Studio -> Tools -> NuGet Package Manager -> Manage NuGet Packages for Solution...
2. Search for Kentico.
3. Install the necessary packages.

## Kentico.Web.Mvc integration package

The main purpose of the _Kentico.Web.Mvc_ integration package is to help you [start developing](https://docs.kentico.com/k9/developing-websites/developing-sites-using-asp-net-mvc/starting-with-mvc-development.md) your [MVC applications](https://docs.kentico.com/k9/developing-websites/developing-sites-using-asp-net-mvc.md) with as few manual steps as possible. The package contains the necessary items to make your MVC application work with the Kentico application.

The package has a dependency on the [Kentico.Libraries](#kentico.libraries-integration-package) integration package, so the installation automatically includes all Kentico assemblies that you need in an external application.

Additionally, the Kentico.Web.Mvc integration package allows you to use the following features:

- Preview mode
- [Data annotation localization](https://docs.kentico.com/k9/developing-websites/developing-sites-using-asp-net-mvc/developing-mvc-applications/localizing-data-on-mvc-sites.md)
- [Global Not Found feature](https://docs.kentico.com/k9/developing-websites/developing-sites-using-asp-net-mvc/developing-mvc-applications/adding-preview-mode-support-for-mvc-sites.md)

To use other features, you need to separately install the corresponding packages listed in the [General integration packages](#general-integration-packages) section.

## Kentico.Libraries integration package

NuGet package containing all the Kentico assemblies that you need for working with Kentico in an external application.

> **Note:** **Important**: Always use the _Kentico.Libraries_ package with the same version as the version of your Kentico application. For example, if you're using Kentico 9.0.1, you need to use the 9.0.1 version of the Kentico.Libraries package as well. See how you can [apply a hotfix](https://docs.kentico.com/k9/installation/hotfix-instructions-kentico-9.md) to your Kentico installation.

## General integration packages
