In this part, you will build a new module for placing orders and install it in the main CRM application.

## 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.

Right-click the `modules` folder on the *Solution Explorer* panel, and select the *Add* -> *New Module* -> *Standard Module* command:

![abp-studio-add-new-standard-module](images/abp-studio-add-new-standard-module.png)

That command opens a dialog to define the properties of the new module:

![abp-studio-add-new-standard-module-dialog](images/abp-studio-add-new-standard-module-dialog.png)

Set `ModularCrm.Ordering` as the *Module name*, leave the *Output folder* as is and click the *Next* button.

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.

The same limitation applies to the database selection. You can only choose one database provider for a standard module. Select the *Entity Framework Core* option and click *Next*.

You can uncheck the *Include Tests* option to keep the module simple. Click the *Create* button to create the module.

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:

![file-system-odering-module-initial-folder](images/file-system-ordering-module-initial-folder.png)

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):

## Installing into the Main Application

In this section, we will install the `ModularCrm.Ordering` module in the main application so it can be part of the system.

> Before the installation, please ensure the web application is not running.

Right-click the `ModularCrm` module (under the `main` folder) and select the *Import Module* command:

![abp-studio-import-module-for-ordering](images/abp-studio-import-module-for-ordering.png)

That command opens the *Import Module* dialog:

![abp-studio-import-module-for-ordering-dialog](images/abp-studio-import-module-for-ordering-dialog.png)

Select the `ModularCrm.Ordering` module and check the *Install this module* option as shown in the preceding figure. When you click the OK button, a new dialog is shown to select the packages to install:

![abp-studio-install-module-dialog](images/abp-studio-install-module-dialog.png)

Select the `ModuleCrm.Ordering` and `ModularCrm.Ordering.UI` packages from the left area and the `ModularCrm` package from the middle area as shown in the preceding figure. Finally, click *OK*.

In this part of the tutorial, we've created a standard module. This allows you to create modules or applications with a different structure. In the next part, we will add functionality to the Ordering module.
