-description: """
-Lambda-term is a cross-platform library for manipulating the terminal. It
-provides an abstraction for keys, mouse events, colors, as well as a set of
-widgets to write curses-like applications. The main objective of lambda-term is
-to provide a higher level functional interface to terminal manipulation than,
-for example, ncurses, by providing a native OCaml interface instead of bindings
-to a C library. Lambda-term integrates with zed to provide text edition
-facilities in console applications."""

+
+This library provides a lean alternative to the Format [1] module of
+the OCaml standard library. It aims to make it easy for users to do
+the right thing. If you have tried Format before but find its API
+complicated and difficult to use, then Pp might be a good choice for
+you.
+
+Pp uses the same concepts of boxes and break hints, and the final
+rendering is done to formatter from the Format module. However it
+defines its own algebra which some might find easier to work with and
+reason about. No previous knowledge is required to start using this
+library, however the various guides for the Format module such as this
+one [2] should be applicable to Pp as well.
