+IIS Modules
+-----------
+
+The Kanboard archive contains a `web.config` file to enable [URL rewriting](nice-urls.markdown). 
+This configuration require the [Rewrite module for IIS](http://www.iis.net/learn/extensions/url-rewrite-module/using-the-url-rewrite-module).
+
+If you don't have the rewrite module, you will get an internal server error (500) from IIS.
+If you don't want to have Kanboard with nice URLs, you can remove the file `web.config`.
