-This command:
-
-* Runs the Read OCR container from the container image.
-* Allocates 8 CPU core and 18 gigabytes (GB) of memory.
-* Exposes TCP port 5000 and allocates a pseudo-TTY for the container.
-* Automatically removes the container after it exits. The container image is still available on the host computer.

-You can alternatively run the container using environment variables:

 ### Asynchronous Read
 
-# [Version 3.2 model 2021-09-30-preview](#tab/version-3-2-model-2021-09-30-preview)
-
-You can use the `POST /vision/v3.2/read/analyze` and `GET /vision/v3.2/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.
-
-
-From the swagger UI, select the `Analyze` to expand it in the browser. Then select **Try it out** > **Choose file**. In this example, we'll use the following image:
-
-![tabs vs spaces](media/tabs-vs-spaces.png)
-
-When the asynchronous POST has run successfully, it returns an **HTTP 202** status code. As part of the response, there is an `operation-location` header that holds the result endpoint for the request.
