 ### Asynchronous read
 
-You can use the `POST /vision/v2.1/read/core/asyncBatchAnalyze` and `GET /vision/v2.1/read/operations/{operationId}` operations in concert to asynchronously read an image, similar to how the Computer Vision service uses those corresponding REST operations. The asynchronous POST method will return an `operationId` that is used as the identifer to the HTTP GET request.

 ### Asynchronous text recognition
 
-You can use the `POST /vision/v2.1/recognizeText` and `GET /vision/v2.1/textOperations/*{id}*` operations in concert to asynchronously recognize printed text in an image, similar to how the Computer Vision service uses those corresponding REST operations. The Recognize Text container only recognizes printed text, not handwritten text, at this time, so the `mode` parameter normally specified for the Computer Vision service operation is ignored by the Recognize Text container.

Because this operation is synchronous, the request body for this operation is the same as the `POST /vision/v2.1/recognizeText` operation, but the response body for this operation is the same as that returned by the `GET /vision/v2.1/textOperations/*{id}*` operation.
