 # Context
 
+The **Context** module provides context for abilities or applications. It allows access to application-specific resources, as well as permission requests and verification.
+
 > **NOTE**
-> 
-> The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.

 ## Usage
 
-The **Context** object is created in a **featureAbility** and returned through its **getContext()** API. Therefore, you must import the **@ohos.ability.featureAbility** package before using the Context module. An example is as follows:

+The **AbilityDelegator** module provides APIs for managing **AbilityMonitor** instances that are used to monitor the lifecycle state changes of a specified ability. You can use the APIs to add and remove **AbilityMonitor** instances, wait for an ability to reach the **OnCreate** lifecycle state, set the waiting time, obtain the lifecycle state of an ability, obtain the top ability of the current application, and start an ability.
