 ## Overview
 
-AppStorage is a singleton LocalStorage object that is created by the UI framework at application startup. Its purpose is to provide the central storage for mutable application UI state attributes. AppStorage retains all those attributes and their values as long as the application remains running. Attributes are accessed using a unique key string value.

 ## \@StorageProp
 
-As mentioned above, if you want to establish a binding between AppStorage and a custom component, you need to use the \@StorageProp and \@StorageLink decorators. Use \@StorageProp(key) or \@StorageLink(key) to decorate variables in the component. **key** identifies the attribute in AppStorage.
+As mentioned above, if you want to establish a binding between AppStorage and a custom component, you'll need the \@StorageProp and \@StorageLink decorators. Use \@StorageProp(key) or \@StorageLink(key) to decorate variables in the component, where **key** identifies the attribute in AppStorage.
 
 When a custom component is initialized, the \@StorageProp(key)/\@StorageLink(key) decorated variable is initialized with the value of the attribute with the given key in AppStorage. Local initialization is mandatory. If an attribute with the given key is missing from AppStorage, it will be added with the stated initializing value. (Whether the attribute with the given key exists in AppStorage depends on the application logic.)

 - A call to **PersistentStorage.PersistProp()** after creating the attribute in AppStorage uses the type and value in AppStorage and overwrites any attribute with the same name in PersistentStorage. In light of this, the opposite order of calls is recommended. For an example of incorrect usage, see [Accessing Attribute in AppStorage Before PersistentStorage](arkts-persiststorage.md#accessing-attribute-in-appstorage-before-persistentstorage).
 
 - A call to **Environment.EnvProp()** after creating the attribute in AppStorage will fail. This is because AppStorage already has an attribute with the same name, and the environment variable will not be written into AppStorage. Therefore, you are advised not to use the preset environment variable name in AppStorage.

Do not assign values to \@ObjectLink decorated variables, as doing so will interrupt the synchronization chain. \@ObjectLink decorated variables are initialized through data source (Object) references. Assigning a value to them is equivalent to updating the array item or class attribute in the parent component, which is not supported in TypeScript/JavaScript and will result in a runtime error.
