 # Installing and Uninstalling Packages
 
 This article will cover the process of installing as well as uninstalling packages from your Umbraco CMS website.
 
-As the article will cover both NuGet packages and zip file packages, it is important to know the distinction:
-
-* **NuGet packages**: Modern Umbraco (Umbraco 10+) and Legacy Umbraco (Umbraco 8 and earlier versions).
-* **Package zip files**: Legacy Umbraco (Umbraco 8 and earlier versions) only.

 ## Installing packages
 
 In the Umbraco Backoffice, you will find a **Packages** section that displays the [Umbraco Marketplace](https://marketplace.umbraco.com/). From here you can browse all community-made as well as official Umbraco packages for the Umbraco CMS.
