 # Building on Windows
 
-Compiling on Windows is a bit more involved. You will need to install these *in this order*. This should give you a working environment to compile native node.js bindings. The [node-gyp](https://github.com/TooTallNate/node-gyp) repo also has some documentation on getting things working with Windows. It's possible it will also work with VS2012, but it's untested. I use [veewee](https://github.com/jedi4ever/veewee) for testing with clean versions of Windows and this process does work. If you have problems, it's most likely something else that's installed conflicting with the build environment.
