+# Controllers from scratch
+
+This example folder shows how I started to develop
+the Controller idea inside the Iris web framework itself.
+
+Now it's built'n feature and can be used as:
+
+```go
+// +build go1.9
+
+// file main.go
+package main
+
+import (
+    "github.com/kataras/iris/_examples/routing/mvc/persistence"
+
+    "github.com/kataras/iris"
+)
+
+func main() {
+    app := iris.New()
+    app.RegisterView(iris.HTML("./views", ".html"))
+
+    db := persistence.OpenDatabase("a fake db")
+
+    app.Controller("/user/{userid:int}", NewUserController(db))
+
+	// http://localhost:8080/
+    // http://localhost:8080/user/42
+    app.Run(iris.Addr(":8080"))
+}
+```
+
+```go
+// +build go1.9
+
+// file user_controller.go
+package main
+
+import (
+    "time"
+
+    "github.com/kataras/iris/_examples/routing/mvc/persistence"
+
+    "github.com/kataras/iris"
+)
+
+// User is our user example controller.
+type UserController struct {
+    iris.Controller
+
+	// All fields that are tagged with iris:"persistence"`
+	// are being persistence and kept between the different requests,
+	// meaning that these data will not be reset-ed on each new request,
+	// they will be the same for all requests.
+    CreatedAt time.Time             `iris:"persistence"`
+    Title     string                `iris:"persistence"`
+    DB        *persistence.Database `iris:"persistence"`
+}
+
+func NewUserController(db *persistence.Database) *User {
+    return &UserController{
+        CreatedAt: time.Now(),
+        Title:     "User page",
+        DB:        db,
+    }
+}
+
+// Get serves using the User controller when HTTP Method is "GET".
+func (c *UserController) Get() {
+    c.Tmpl = "user/index.html"
+    c.Data["title"] = c.Title
+    c.Data["username"] = "kataras " + c.Params.Get("userid")
+    c.Data["connstring"] = c.DB.Connstring
+    c.Data["uptime"] = time.Now().Sub(c.CreatedAt).Seconds()
+}
+
+/* Can use more than one, the factory will make sure
+that the correct http methods are being registed  for this
+controller, uncommend these if you want:
+
+func (c *User) Post() {}
+func (c *User) Put() {}
+func (c *User) Delete() {}
+func (c *User) Connect() {}
+func (c *User) Head() {}
+func (c *User) Patch() {}
+func (c *User) Options() {}
+func (c *User) Trace() {}
+*/
+
+/*
+func (c *User) All() {}
+//        OR
+func (c *User) Any() {}
+*/
+```
+
