-# \@Builder: Custom Builder Function
+# \@Builder Decorator: Custom Builder Function
 
 
 As previously described, you can reuse UI elements by creating a custom component, which comes with a fixed internal UI structure and allows for data transfer only with its caller. ArkUI also provides a more lightweight mechanism for reusing UI elements: \@Builder. An \@Builder decorated function is a special function that serves similar purpose as the build function. The \@Builder function body follows the same syntax rules as the **build** function. You can abstract reusable UI elements into a method and call the method in **build**.

en/application-dev/quick-start/arkts-builderparam.md

-# \@BuilderParam: @Builder Function Reference
+# \@BuilderParam Decorator: @Builder Function Reference
 
 
 In certain circumstances, you may need to add a specific function, such as a click-to-jump action, to a custom component. However, embedding an event method directly inside of the component will add the function to all places where the component is imported. This is where the \@BuilderParam decorator comes into the picture. \@BuilderParam is used to decorate a custom component member variable of type reference to an \@Builder method. When initializing a custom component, you can assign a value to the variable, thereby adding the specific function to the custom component. This decorator can be used to declare an element of any UI description, similar to a slot placeholder.

 The decorators described above can observe only the changes of the first layer. However, in real-world application development, the application may encapsulate its own data model based on development requirements. In the case of multi-layer nesting, for example, a two-dimensional array, an array item class, or a class insider another class as an attribute, the attribute changes at the second layer cannot be observed. This is where the \@Observed and \@ObjectLink decorators come in handy.

-1. If you are opening DevEco Studio for the first time, click **Create Project**. If a project is already open, choose **File** > **New** > **Create Project** from the menu bar. On the **Choose Your Ability Template** page, select **Application** (or **Atomic Service**, depending on your project), select **Empty Ability** as the template, and click **Next**.
+The procedure for creating a project varies, depending on whether the API version is later than 9 or not.
+
+The following describes how to create the OpenHarmony projects of API 10 and API 9.
+
