+
+### Creating Custom Routes in ASP.NET MVC App
+
+* Using `MapRoute` extension method.
+* Need provide at least **route name** & **URL patter**.
+* Default parameter is optional
+* Multiple custom routes can be created with different names
+
+```csharp
+namespace FirstMVCDemo
+{
+    public class RouteConfig
+    {
+        public static void RegisterRoutes(RouteCollection routes)
+        {
+            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
+
+            routes.MapRoute(
+                name: "Employee",
+                url: " Employee/{id}",
+                defaults: new 
+                { 
+                    controller = "Employee", 
+                    action = "Index" 
+                }
+            );
+            
+            routes.MapRoute(
+                name: "Default", //Route Name
+                url: "{controller}/{action}/{id}", //Route Pattern
+                defaults: new
+                {
+                    controller = "Home", //Controller Name
+                    action = "Index", //Action method Name
+                    id = UrlParameter.Optional //Defaut value for above defined parameter
+                }
+            );
+        }
+    }
+}
+```
+
+Following URLs will be mapped to Employee route:
+* `http://localhost:xxxxx/Employee`
+* `http://localhost:xxxxx/Employee/Index`
+* `http://localhost:xxxxx/Employee/Index/3`
+
+Rules of creating route:
