 ## Introduction
 
 `htop` is a cross-platform interactive process viewer.
-It requires `ncurses`.
 
-For more information and details on how to contribute to `htop`
-visit [htop.dev](https://htop.dev).
+`htop` allows scrolling the list of processes vertically and horizontally to see their full command lines and related information like memory and CPU consumption.
+
+The information displayed is configurable through a graphical setup and can be sorted and filtered interactively.
+
+Tasks related to processes (e.g. killing and renicing) can be done without entering their PIDs.
+
+Running `htop` requires `ncurses` libraries (typically named libncursesw*).
