+### Download the Source Code
+
+This tutorials has multiple versions based on your **UI** and **Database** preferences. We've prepared two combinations of the source code to be downloaded:
+
+* [MVC (Razor Pages) UI with EF Core](https://github.com/abpframework/abp-samples/tree/master/BookStore-Mvc-EfCore)
+* [Angular UI with MongoDB](https://github.com/abpframework/abp-samples/tree/master/BookStore-Angular-MongoDb)
+
+## Introduction
+
+In the previous parts, we've used the ABP infrastructure to easily build some services;
+
+* Used the [CrudAppService](../Application-Services.md) base class instead of manually developing an application service for standard create, read, update and delete operations.
+* Used [generic repositories](../Repositories.md) to completely automate the database layer.
+* Used [conventional API controllers](../API/Auto-API-Controllers.md) instead of manually writing API controllers.
+
+For the "Authors" part, we will do most of the things manually to show how you can do it in case of need.
+
+## The Author Entity
+
+Create an `Authors` folder (namespace) in the `Acme.BookStore.Domain` project and add an `Author` class inside it:
+
+````csharp
+using System;
+using Volo.Abp.Domain.Entities.Auditing;
+
+namespace Acme.BookStore.Authors
+{
+    public class Author : FullAuditedAggregateRoot<Guid>
+    {
+        public string Name { get; internal set; }
+
+        public DateTime BirthDate { get; set; }
+
+        public string ShortBio { get; set; }
+    }
+}
+````
+
+* Inherited from `FullAuditedAggregateRoot<Guid>` which makes the entity [soft delete](../Data-Filtering.md) (that means when you delete it, it is not deleted in the database, but just marked as deleted) with all the [auditing](../Entities.md) properties.
+* `internal set` for the `Name` property restricts to set this property from out of the domain layer. Because we want to change it in a controlled way in the domain layer to prevent to create two authors with the same name, to just demonstrate a simple business rule.
