 ## Creating a Standard Module
 
-In this part, we have used the *DDD Module* template for the Product module and will use the *Standard Module* template for the Ordering module.
+In the first part of this tutorial, you created the `ModularCrm` solution with modularity enabled by selecting the _Setup as a modular solution_ option. At that time, you also created your first module - `ModularCrm.Catalog` - using the *Standard Module* template.
 
-Right-click the `modules` folder on the *Solution Explorer* panel, and select the *Add* -> *New Module* -> *Standard Module* command:
+Now, you will create a second module for the `ModularCrm` solution through ABP Studio. This new module, called `Ordering`, will handle all order related functionality in the application.

+To add a new module, right-click the `modules` folder on the *Solution Explorer* panel, and select the *Add* -> *New Module* -> *Standard Module* command:

-Similar to DDD module creation, you can choose the type of UI you want to support in your module or select *No UI* if you don't need a user interface. In this example, we'll select the *MVC* option and click *Next*. One difference is that, for a standard module, you can only choose one UI type.

-Since we've created a standard module, it doesn't have multiple layers like the DDD module. If you open the `modules/modularcrm.ordering` in your file system, you can see the initial files:

-Because only a single UI package can be chosen, the UI type doesn’t matter. This is why the package name is changed to *ModularCrm.Ordering.UI*. Additionally, there are no *Domain*, *EntityFrameworkCore*, or *Http* layers like in the DDD module. We're going to use the `ModularCrm.Ordering` package for the domain business logic. You can open `ModularCrm.Ordering.sln` in your favorite IDE (e.g. Visual Studio):
