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/k10/developing-websites/developing-sites-using-asp-net-mvc/starting-with-mvc-development.md) your [MVC applications](https://docs.kentico.com/k10/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: - [Data annotation localization](https://docs.kentico.com/k10/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/k10/developing-websites/developing-sites-using-asp-net-mvc/developing-mvc-applications/handling-404-not-found-globally-in-mvc-applications.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 to work with Kentico in an external application. Installation automatically includes the _Kentico.Libraries.Dependencies_ package, which provides third-party libraries that are required for the Kentico API to work correctly. > **Note:** **Important**: Always use the _Kentico.Libraries_ package with the same version as the version of your Kentico application. For example, if you are using Kentico 10.0.1, you need to use the 10.0.1 version of the _Kentico.Libraries_ package. See how you can [apply a hotfix](https://docs.kentico.com/k10/installation/hotfix-instructions-kentico-10.md) to your Kentico installation. > > **Note**: If you install the _Kentico.Libraries_ package in a class library project and later include the class library project in a web application project that doesn't contain the _Kentico.Web.Mvc_ package, you must install _Kentico.Libraries_ package in the web application project as well. ## General integration packages ### Kentico.LanguagePack.English NuGet package containing files required for the English localization of Kentico.
