 `htop` is a cross-platform interactive process viewer.
 
 `htop` allows scrolling the list of processes vertically and horizontally to see their full command lines and related information like memory and CPU consumption.
+Also system wide information, like load average or swap usage, is shown.
 
 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*).

 `htop` has a set of fixed optional dependencies, depending on build/configure option used:
-* `libdl`, if not building static and support for some of the optional libraries is enabled, is always required when support for to optionally load dependencies (i.e. `libsensors`, `systemd`) is present.

-* `systemd` is optional when `--enable-static` was not used to configure `htop` (Linux only). If building statically and `libsystemd` is not found by `configure` support for the SystemD meter is disabled entirely.
