+              Functional Terminal (X) User interface
+              
+              A simple C++ library for terminal based user interfaces!
+              Feature
+              - Functional style. Inspired by [1] and React
+              - Simple and elegant syntax (in my opinion)
+              - Keyboard & mouse navigation.
+              - Support for UTF8 and fullwidth chars (→ 测试)
+              - Support for animations. Demo 1, Demo 2
+              - Support for drawing. Demo
+              - No dependencies
+              - Cross platform: Linux/MacOS (main target), WebAssembly, Windows (Thanks to contributors!).
+              - Learn by examples, and tutorials
+              - Multiple packages: CMake FetchContent (preferred), vcpkg, pkgbuild, conan, nix, etc...
+              - Good practises: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...
