 # termbox2
 
-termbox2 is a terminal rendering library that retains the [suckless][0] spirit
-of the original [termbox][1] (simple API, no dependencies beyond libc) and adds
-some improvements (strict error checking, more efficient escape sequence
-parsing, code gen for built-in escape sequences, opt-in support for 32-bit
-color, extended grapheme clusters, test suite). termbox2 is organized as a
-single file header library, though it is possible to compile it as a
-stand-alone shared or static library.
+termbox2 is a terminal rendering library for creating TUIs. It is a
+[suckless](https://suckless.org) alternative to the ubiquitous
+[ncurses](https://invisible-island.net/ncurses/) library. It ships with built-in
+support for popular terminals and can also fallback to terminfo if present.
