+[KindNES] by [@henryksloan]
+is a new NES emulator that supports sound, controllers, and
+much of the NES library.
+
+KindNES is designed to strike a balance between performance, hardware accuracy,
+and code clarity. It directly emulates the CPU, graphics, and sound of the NES
+with minimal approximation. The code is intended to pair well with the NESdev
+wiki as a resource for learning about the NES.
+
+KindNES is in a playable state, and is approaching a release version.
+Features planned before release include saving and an improved cross-platform
+GUI.
