 ## Middleware information
 
-This folder contains a middleware for the  build'n Iris logger but for the requests.
+This folder contains a middleware which is a bridge between Iris station's logger and http requests.
+
+**Logs the incoming requests**
 
 ## How to use
-```go
 
-package main
-
-import (
-	"github.com/kataras/iris"
-	"github.com/kataras/iris/middleware/logger"
-)
-
-func main() {
-
-	iris.UseFunc(logger.Default())
-	// or iris.Use(logger.DefaultHandler())
-	// or iris.UseFunc(iris.HandlerFunc(logger.DefaultHandler())
-	// or iris.Get("/", logger.Default(), func (ctx *iris.Context){})
-	// or iris.Get("/", iris.HandlerFunc(logger.DefaultHandler()), func (ctx *iris.Context){})
-
-	// Custom settings:
-	// ...
-	// iris.UseFunc(logger.Custom(writer io.Writer, prefix string, flag int))
-	// and so on...
-
-	// Custom options:
-	// ...
-	// iris.UseFunc(logger.Default(logger.Options{IP:false}))  // don't log the ip
-	// or iris.UseFunc(logger.Custom(writer io.Writer, prefix string, flag int, logger.Options{IP:false}))
-	// and so on...
-
-	iris.Get("/", func(ctx *iris.Context) {
-		ctx.Write("hello")
-	})
-
-	iris.Get("/1", func(ctx *iris.Context) {
-		ctx.Write("hello")
-	})
-
-	iris.Get("/3", func(ctx *iris.Context) {
-		ctx.Write("hello")
-	})
-
-	// IF YOU WANT LOGGER TO LOGS THE HTTP ERRORS ALSO THEN:
-	// FUTURE: iris.OnError(404, logger.Default(logger.Options{Latency: false}))
-
-	// NOW:
-	errorLogger := logger.Default(logger.Options{Latency: false}) //here we just disable to log the latency, no need for error pages I think
-	// yes we have options look at the logger.Options inside middleware/logger.go
-	iris.OnError(404, func(ctx *iris.Context) {
-		errorLogger.Serve(ctx)
-		ctx.Write("My Custom 404 error page ")
-	})
-	//
-
-	println("Server is running at :80")
-	iris.Listen(":80")
