+## Intro
+
+Nah, not another **Web Framework**, we have that enough.The more we spend on [Go](http://golang.org/), the more clearly we realize that most lightweight, pure-stdlib conventions really do scale to large groups of developers and diverse project ecosystems. You absolutely don’t need a *Web Framework* like you normally do in other languages, simply because your code base has grown beyond a certain size. Or you believe it might grow beyond a certain size! You truly ain’t gonna need it. What we really need is just a suitable routing system, along with some common toolkits for web development, the standard idioms and practices will continue to function beautifully at scale.

 ## Getting Started
 
 Install the package, along with executable binary helper (**go 1.4** and greater is required):

router.go

 	return router
 }
 
-// FileRouter registers a handler to serve HTTP requests
+// FileServer registers a handler to serve HTTP requests
 // with the contents of the file system rooted at root.
 func (self *Router) FileServer(prefix, dir string) {
 	if abs, err := filepath.Abs(dir); err == nil {
+		Infof("FS: %s", abs)
 		fs := http.StripPrefix(prefix, http.FileServer(http.Dir(abs)))
 		self.mux.PathPrefix(prefix).Handler(fs)
 	} else {
