+
+## What is bone ?
+
+Bone is a lightweight and lightning fast HTTP Multiplexer for Golang. It support :
+
+- URL Parameters
+- REGEX Parameters
+- Wildcard routes
+- Router Prefix
+- Sub Router, `mux.SubRoute()`, support most standard router (bone, gorilla/mux, httpRouter etc...)
+- Http method declaration
+- Support for `http.Handler` and `http.HandlerFunc`
+- Custom NotFound handler
+- Respect the Go standard `http.Handler` interface
+
+![alt tag](https://c2.staticflickr.com/2/1070/540747396_5542b42cca_z.jpg)
+
+## Speed
+
+```
+- BenchmarkBoneMux        10000000               118 ns/op
+- BenchmarkZeusMux          100000               144 ns/op
+- BenchmarkHttpRouterMux  10000000               134 ns/op
+- BenchmarkNetHttpMux      3000000               580 ns/op
+- BenchmarkGorillaMux       300000              3333 ns/op
+- BenchmarkGorillaPatMux   1000000              1889 ns/op
+```
+
+ These test are just for fun, all these router are great and really efficient.
+ Bone do not pretend to be the fastest router for every job.
+
+## Example
+
+``` go
+
+package main
+
+import(
+  "net/http"
+
+  "github.com/go-zoo/bone"
+)
+
+func main () {
+  mux := bone.New()
+
+  // mux.Get, Post, etc ... takes http.Handler
+  mux.Get("/home/:id", http.HandlerFunc(HomeHandler))
+  mux.Get("/profil/:id/:var", http.HandlerFunc(ProfilHandler))
+  mux.Post("/data", http.HandlerFunc(DataHandler))
+
+  // Support REGEX Route params
+  mux.Get("/index/#id^[0-9]$", http.HandlerFunc(IndexHandler))
+
+  // Handle take http.Handler
+  mux.Handle("/", http.HandlerFunc(RootHandler))
+
+  // GetFunc, PostFunc etc ... takes http.HandlerFunc
+  mux.GetFunc("/test", Handler)
+
+  http.ListenAndServe(":8080", mux)
+}
+
+func Handler(rw http.ResponseWriter, req *http.Request) {
+  // Get the value of the "id" parameters.
+  val := bone.GetValue(req, "id")
+
+  rw.Write([]byte(val))
+}
+
+```
