+# Nitrogen Desktop Experience (NDE)
+This is a project I've had ideas about for a few years.  The end goal is to create a DE
+(Desktop Environment) that can alter itself at runtime using various desktop agents which
+dictate the look and feel.
+
+For example:
+
++ A default desktop agent which provides a basic usable desktop
++ Another desktop agent to provide a macOS-like look and feel
++ A third desktop agent better suited for small screens, like phones and tablets
+
+---
+## Components
++ [`libnde`](src/libnde) : Library containing common components
++ [`libntk`](src/libntk) : Nitrogen ToolKit - all the GUI stuffies, API based on Java Swing and [Xwing](https://github.com/qrux/xwing/)
++ [`NitroWin`](src/NitroWin) : Nitrogen Window Manager
+
+---
+## Documents
+None yet.  :crying_cat_face:
+
+---
+## Requirements
++ [FreeBSD](http://freebsd.org/) `>= 10.1` (tested using FreeBSD 11)
++ [`x11/libX11`](https://www.freshports.org/x11/libX11/)
++ [`x11/xproto`](https://www.freshports.org/x11/xproto/)
++ [`devel/cmake`](https://www.freshports.org/devel/cmake/)
++ [`devel/cmake-modules`](https://www.freshports.org/devel/cmake-modules/)
