-## Description
-
-dial-stdio uses the stdin and stdout streams of the command to proxy to the configured builder instance.
-It is not intended to be used by humans, but rather by other tools that want to interact with the builder instance via BuildKit API.
-
-## Examples
-
-Example go program that uses the dial-stdio command wire up a buildkit client.
-This is for example use only and may not be suitable for production use.
-
-```go
-client.New(ctx, "", client.WithContextDialer(func(context.Context, string) (net.Conn, error) {
-    c1, c2 := net.Pipe()
-    cmd := exec.Command("docker", "buildx", "dial-stdio")
-    cmd.Stdin = c1
-    cmd.Stdout = c1
-
-    if err := cmd.Start(); err != nil {
-        c1.Close()
-        c2.Close()
-        return nil, err

-If `RECLAIMABLE` is false, the `docker buildx du prune` command won't delete
-the record, even if you use `--all`. That's because the record is actively in
-use by some component of the builder.
-
-The asterisks (\*) in the default output indicate the following:
-
-- An asterisk next to an ID (`zu7m6evdpebh5h8kfkpw9dlf2*`) indicates that the record
-  is mutable. The size of the record may change, or another build can take ownership of
-  it and change or commit to it. If you run the `du` command again, this item may
-  not be there anymore, or the size might be different.
-- An asterisk next to a size (`8.288kB*`) indicates that the record is shared.
-  Storage of the record is shared with some other resource, typically an image.
-  If you prune such a record then you will lose build cache but only metadata
-  will be deleted as the image still needs to actual storage layers.

 Each builder has one or more nodes associated with it. The current builder's
 name is marked with a `*` in `NAME/NODE` and explicit node to build against for
 the target platform marked with a `*` in the `PLATFORMS` column.
-
-## Examples
-
-### <a name="format"></a> Format the output (--format)
-
-The formatting options (`--format`) pretty-prints builder instances output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-| Placeholder       | Description                                 |
-|-------------------|---------------------------------------------|
-| `.Name`           | Builder or node name                        |
-| `.DriverEndpoint` | Driver (for builder) or Endpoint (for node) |
-| `.LastActivity`   | Builder last activity                       |
-| `.Status`         | Builder or node status                      |
-| `.Buildkit`       | BuildKit version of the node                |
-| `.Platforms`      | Available node's platforms                  |
-| `.Error`          | Error                                       |
-| `.Builder`        | Builder object                              |
-
-When using the `--format` option, the `ls` command will either output the data
-exactly as the template declares or, when using the `table` directive, includes
-column headers as well.
-
-The following example uses a template without headers and outputs the
-`Name` and `DriverEndpoint` entries separated by a colon (`:`):
-
-```console
-$ docker buildx ls --format "{{.Name}}: {{.DriverEndpoint}}"
-elated_tesla: docker-container
-elated_tesla0: unix:///var/run/docker.sock
-elated_tesla1: ssh://ubuntu@1.2.3.4
-default: docker
-default: default
-```
-
-The `Builder` placeholder can be used to access the builder object and its
-fields. For example, the following template outputs the builder's and
-nodes' names with their respective endpoints:
-
-```console
-$ docker buildx ls --format "{{.Builder.Name}}: {{range .Builder.Nodes}}\n  {{.Name}}: {{.Endpoint}}{{end}}"
-elated_tesla:
-  elated_tesla0: unix:///var/run/docker.sock
-  elated_tesla1: ssh://ubuntu@1.2.3.4
-default: docker
-  default: default
