 The multi-HAP mechanism is used to facilitate modular management for developers. There is no one-to-one mapping between the HAP and the running process of the application. The detailed running mechanism is as follows:
 
 
-- By default, all UIAbility, ServiceExtensionAbility, and DataShareExtensionAbility components of an application (with the same bundle name) run in the same independent process, and other ExtensionAbility components of the same type run in separate processes.
+- By default, all UIAbility, ServiceExtensionAbility, and DataShareExtensionAbility components of an application (with the same bundle name) run in the same independent process (known as the main process), and other ExtensionAbility components of the same type run in separate processes.
 
 - The HAP file supports the process configuration through the **process** tag in the **module.json5** (stage model) or **config.json** (FA model) file. This feature is supported only by system applications. If **process** is configured for an HAP file, all components of the HAP file run in an independent process. Multiple HAP files can be configured with the same process, in which case the HAP files run in the same process. For details about the process configuration, see [module.json5 Configuration File](module-configuration-file.md).

 # 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.

+# @ohos.font (Custom Font Registration)
+
+The **font** module provides APIs for registering custom fonts.
+
+> **NOTE**
+>
+> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+
+## Modules to Import
+
+```ts
+import font from '@ohos.font'
+```
+
+## font.registerFont
+
+registerFont(options: FontOptions): void
+
+Registers a custom font with the font manager.
+
+**System capability**: SystemCapability.ArkUI.ArkUI.Full
