 ## Blog routing
 
 Our blog's main routing rules are as follows:
 
-	//Show blog Home
-	beego.RegisterController("/", &controllers.IndexController{})
-	//View blog details
-	beego.RegisterController("/view/: id([0-9]+)", &controllers.ViewController{})
-	//Create blog Bowen
-	beego.RegisterController("/new", &controllers.NewController{})
-	//Delete Bowen
-	beego.RegisterController("/delete/: id([0-9]+)", &controllers.DeleteController{})
-	//Edit Bowen
-	beego.RegisterController("/edit/: id([0-9]+)", &controllers.EditController{})
+```
+//Show blog Home
+beego.RegisterController("/", &controllers.IndexController{})
+//View blog details
+beego.RegisterController("/view/: id([0-9]+)", &controllers.ViewController{})
+//Create blog Bowen
+beego.RegisterController("/new", &controllers.NewController{})
+//Delete Bowen
+beego.RegisterController("/delete/: id([0-9]+)", &controllers.DeleteController{})
+//Edit Bowen
+beego.RegisterController("/edit/: id([0-9]+)", &controllers.EditController{})
+```
+
 
 ## Database structure
 
 A trivial database table to store basic blog information:
 
-	CREATE TABLE entries (
-	    id INT AUTO_INCREMENT,
-	    title TEXT,
-	    content TEXT,
-	    created DATETIME,
-	    primary key (id)
-	);
+```
+CREATE TABLE entries (
+    id INT AUTO_INCREMENT,
+    title TEXT,
+    content TEXT,
+    created DATETIME,
+    primary key (id)
+);
+```
