 # YARP Lets Encrypt
 
+> [!NOTE]
+> The [`LettuceEncrypt` NuGet package](https://github.com/natemcmaster/LettuceEncrypt) described in this article is archived and no longer supported, so the package isn't recommended for use.

 ## Introduction
-YARP can support the certificate authority [Lets Encrypt](https://letsencrypt.org/) by using the API of another ASP.NET Core project [LettuceEncrypt](https://github.com/natemcmaster/LettuceEncrypt). It allows you to set up TLS between the client and YARP with minimal configuration.
