+dukluv
+======
+
+LibUV bindings for duktape JS engine
+
+The goal of this project is to make a node.js-like environment that's ultra lean for tiny devices.
+
+<http://dukluv.io/>
+
+Prerequisites
+-------------
+
+Linux:
+
+    $ sudo apt-get build-essential
+    $ sudo apt-get install cmake
+
+OS X (using Brew)
+
+    $ brew install cmake
+
+Windows
+
+- Install cmake manually
+- Use cygwin or start an MSVC command prompt
+
+Compiling
+---------
+
+    $ git submodule init; git submodule update
+    $ mkdir build
+    $ cd build
+    $ cmake ..
+    $ make
+
+The result is `./dukluv`, a standalone binary which you can add to
+PATH or copy to e.g. `/usr/local/bin/`.
