 # Approver
 
-Approver module is used to handle approval requests including `CreateBucketApproval`, `MigrateBucketApproval` and `CreateObjectApproval`. The workflow of Approver users can refer [GetApproval](../workflow/workflow.md#get-approval).

 Approver interface inherits [Modular interface](./common/lifecycle_modular.md#modular-interface), so Approver module can be managed by lifecycle and resource manager.
 
-In terms of the functions provided by Approver module, it can be divided into two parts: CreateBucketApproval and CreateObjectApproval. Both CreateBucketApproval and CreateObjectApproval have three methods: PreXXX, HanldeXXX and PostXXX. Therefore, if you can rewrite these methods to meet your own requirements.
+The functionality of the Approver module is primarily centered around the MigrateBucketApproval process. This process encompasses three distinct phases, each managed by a dedicated method: PreXXX for preliminary actions, HandleXXX for core processing, and PostXXX for follow-up operations. Users have the flexibility to customize these methods to align with their specific needs, enabling a tailored approach to the migration process.
 
-As we can see from the second parameter of the methods defined in `Approver` interface, bucketApproval is splitted into `ApprovalCreateBucketTask` and objectApproval is splitted into `ApprovalCreateObjectTask`. They are also defined as an interface.
+The second parameter in PreMigrateBucketApproval(ctx context.Context, task task.ApprovalMigrateBucketTask), which is ApprovalMigrateBucketTask, is also an interface. This design facilitates future customization by the user.
 
-We can query ApprovalCreateBucket and ApprovalCreateObject tasks that we care about by `QueryTasks` method through using subKey.

-ApprovalTask is used to record approval information for users creating buckets and objects. Primary SP approval is required before serving the bucket and object. If the SP approves the message, it will sign the approval message. The greenfield will verify the signature of the approval message to determine whether the SP accepts the bucket and object. ApprovalTask includes `ApprovalCreateBucketTask` and `ApprovalCreateBucketTask`.
