+## Router
+============
+In beego, a route is a struct paired with a URL-matching pattern. The strcut has many method with the same name of http method to server the http request. Each route is associated with a block:
+
+	beego.BeeApp.RegisterController("/", &controllers.MainController{})
+	beego.BeeApp.RegisterController("/admin", &admin.UserController{})
+	beego.BeeApp.RegisterController("/admin/index", &admin.ArticleController{})
+	beego.BeeApp.RegisterController("/admin/addpkg", &admin.AddController{})
+
+You can specify custom regular expressions for routes:
+
+	beego.BeeApp.RegisterController("/admin/editpkg/:id([0-9]+)", &admin.EditController{})
+	beego.BeeApp.RegisterController("/admin/delpkg/:id([0-9]+)", &admin.DelController{})
+	beego.BeeApp.RegisterController("/:pkg(.*)", &controllers.MainController{})
+	
+You can also create routes for static files:
+
+	beego.BeeApp.SetStaticPath("/static","/public")
+	
+this will serve any files in /static, including files in subdirectories. For example request `/static/logo.gif` or `/static/style/main.css` will server with the file in the path `/pulic/logo.gif` or `/public/style/main.css`
