+# SFML 2.4 nuklear backend
+
+This backend provides support for [SFML 2.4](http://liballeg.org/). It will work on all platforms supported by SFML.
+
+## Compiling
+
+You have to edit the Makefile provided so that you can build the demo. Edit the SFML_DIR variable to point to your SFML root folder. This will be the folder to which SFML was installed and contains the lib and include folders.
+
+On Linux there is an extra step. You need to install the the udev development files.
