 ## Implementation Principles

 ![WidgetPrinciple](figures/WidgetPrinciple.png)
 
 - Widget host: an application that displays the widget content and controls the widget location. Only the system application can function as a widget host.
 
 - Widget provider: an application that provides the widget content to display and controls how widget components are laid out and how they interact with users.
 
-- Widget Manager: a resident agent that manages widgets in the system. It provides the [formProvider](../reference/apis/js-apis-app-form-formProvider.md) and [formHost](../reference/apis/js-apis-app-form-formHost.md) APIs as well as widget management, usage, and periodic updates.

 - Widget rendering service: a service that manages widget rendering instances. Widget rendering instances are bound to the [widget components](../reference/arkui-ts/ts-basic-components-formcomponent.md) on the widget host on a one-to-one basis. The widget rendering service runs the widget page code **widgets.abc** for rendering, and sends the rendered data to the corresponding widget component on the widget host.
 
   **Figure 2** Working principles of the ArkTS widget rendering service 
 ![WidgetRender](figures/WidgetRender.png)
 
-Unlike JS widgets, ArkTS widgets support logic code running. To avoid potential ArkTS widget issues from affecting the use of applications, the widget page code **widgets.abc** is executed by the widget rendering service, which is managed by the Widget Manager. Each widget component of a widget host corresponds to a rendering instance in the widget rendering service. Rendering instances of an application provider run in the same virtual machine operating environment, and rendering instances of different application providers run in different virtual machine operating environments. In this way, the resources and state data are isolated between widgets of different application providers. During development, pay attention to the use of the [globalThis](uiability-data-sync-with-ui.md#using-globalthis-between-uiability-and-page) object. Use one **globalThis** object for widgets by the same application provider, and different **globalThis** objects for widgets by different application providers.

+As a quick entry to applications, ArkTS widgets outperform JS widgets in the following aspects:
 
 - Improved development experience and efficiency, thanks to the unified development paradigm

   ArkTS widgets share the same declarative UI development framework as application pages. This means that the page layouts can be directly reused in widgets, improving development experience and efficiency.

 - More widget features
-  - Animation: The ArkTS widget supports the [attribute animation](../reference/arkui-ts/ts-animatorproperty.md) and [explicit animation](../reference/arkui-ts/ts-explicit-animation.md) capabilities, which can be leveraged to deliver a more engaging experience.
-  - Custom drawing: The ArkTS widget allows you to draw graphics with the [Canvas](../reference/arkui-ts/ts-components-canvas-canvas.md) component to present information more vividly.
-  - Logic code execution: The capability to run logic code in widgets means that service logic can be self-closed in widgets, expanding the service application scenarios of widgets.

 ## Release
 When your application package meets the release requirements, you can package and build it into an App Pack and release it to the application market on the cloud. The application market verifies the signature of the App Pack. If the signature verification is successful, the application market obtains the HAP files from the App Pack, signs them, and distributes the signed HAP files.

 # Shared Package Overview
 
-OpenHarmony provides two types of shared packages: [Harmony Achive (HAR)](har-package.md) static shared package and Harmony Shared Package (HSP) dynamic shared package.
+OpenHarmony provides two types of shared packages: [Harmony Archive (HAR)](har-package.md) static shared package and Harmony Shared Package (HSP) dynamic shared package.
 
 Both the HAR and HSP are used to share code and resources and can contain code, C++ libraries, resources, and configuration files. The biggest differences between them are as follows: The code and resources in the HAR are compiled with the invoking module, and if there are multiple invoking modules, the build product contains multiple copies of the same code and resources; the code and resources in the HSP can be compiled independently, and the build product contains only one copy of the code and resources.
