-A minimal TUI [Display Manager/Login
-Manager](https://wiki.archlinux.org/title/Display_manager) written in Rust
-similar to [Ly](https://github.com/nullgemm/ly).
+Lemurs provides a *Terminal User Interface* (TUI) for a [Display/Login
+Managers](https://wiki.archlinux.org/title/Display_manager) in Rust for most
+GNU/Linux and BSD distributions. It can work both with or without SystemD and
+allows for configuration with _One-Time Password_ (OTP) tokens. Lemurs works on
+most Unix systems including Linux, FreeBSD and NetBSD.
 
 ## Goal
 
-The goal of this project is to create a small, robust and yet customizable
-Login Manager which can serve as the front-end to your graphical GNU/Linux.
-Lemurs uses Linux PAM as its method of authentication.
