+toolbox
+=======
+
+Middleware toolbox provides health chcek, pprof, profile and statistic services for [Macaron](https://github.com/go-macaron/macaron).
+
+[API Reference](https://gowalker.org/github.com/go-macaron/toolbox)
+
+### Installation
+
+	go get github.com/go-macaron/toolbox
+	
+## Usage
+
+```go
+// main.go
+import (
+	"gopkg.in/macaron.v1"
+	"github.com/go-macaron/toolbox"
+)
+
+func main() {
+  	m := macaron.Classic()
+  	m.Use(toolbox.Toolboxer(m))
+	m.Run()
+}
+```
+
+Open your browser and visit `http://localhost:4000/debug` to see the effects.
+
+## Options
+
+`toolbox.Toolboxer` comes with a variety of configuration options:
+
+```go
+type dummyChecker struct {
+}
+
+func (dc *dummyChecker) Desc() string {
+	return "Dummy checker"
+}
+
+func (dc *dummyChecker) Check() error {
+	return nil
+}
+
+// ...
+m.Use(toolbox.Toolboxer(m, toolbox.Options{
+	URLPrefix:			"/debug",			// URL prefix for toolbox dashboard.
+	HealthCheckURL:		"/healthcheck", 	// URL for health check request.
+	HealthCheckers: []HealthChecker{
+		new(dummyChecker),
+	},										// Health checkers.
+	HealthCheckFuncs: []*toolbox.HealthCheckFuncDesc{
+		&toolbox.HealthCheckFuncDesc{
+			Desc: "Database connection",
+			Func: func() error { return "OK" },
+		},
+	},										// Health check functions.
+	PprofURLPrefix:		"/debug/pprof/", 	// URL prefix of pprof.
+	ProfileURLPrefix:	"/debug/profile/", 	// URL prefix of profile.
+	ProfilePath:		"profile", 			// Path store profile files.
+}))
+// ...
+```
+
+## Route Statistic
+
+Toolbox also comes with a route call statistic functionality:
+
+```go
+import (
+	"os"
+	"time"
+	//...
+	"github.com/go-macaron/toolbox"
+)
+
+func main() {
+	//...
+	m.Get("/", func(t toolbox.Toolbox) {
+		start := time.Now()
+		
+		// Other operations.
+
