+
+### Formatting
+
+The formatting options (`--format`) pretty-prints tasks output using a Go template.
+
+Valid placeholders for the Go template are listed below:
+
+Placeholder     | Description
+----------------|------------------------------------------------------------------------------------------
+`.ID`           | Task ID
+`.Name`         | Task name
+`.Image`        | Task image
+`.Node`         | Node ID
+`.DesiredState` | Desired state of the task (`running`, `shutdown`, or `accepted`)
+`.CurrentState` | Current state of the task
+`.Error`        | Error
+`.Ports`        | Task published ports
+
+When using the `--format` option, the `stack ps` 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 `Image` entries separated by a colon for all tasks:
+
+```bash
+$ docker stack ps --format "{{.Name}}: {{.Image}}" voting
+voting_worker.1: dockersamples/examplevotingapp_worker:latest
+voting_result.1: dockersamples/examplevotingapp_result:before
+voting_vote.1: dockersamples/examplevotingapp_vote:before
+voting_db.1: postgres:9.4
+voting_redis.1: redis:alpine
+voting_visualizer.1: dockersamples/visualizer:stable
+voting_vote.2: dockersamples/examplevotingapp_vote:before
+voting_redis.2: redis:alpine
+```
+
+### Do not map IDs to Names
+
+The `--no-resolve` option shows IDs for task name, without mapping IDs to Names.
+
+```bash
+$ docker stack ps --no-resolve voting
+ID                  NAME                          IMAGE                                          NODE                        DESIRED STATE  CURRENT STATE            ERROR  PORTS

+
+### Do not truncate output
+
+When deploying a service, docker resolves the digest for the service's
+image, and pins the service to that digest. The digest is not shown by
+default, but is printed if `--no-trunc` is used. The `--no-trunc` option
+also shows the non-truncated task IDs, and error-messages, as can be seen below:
+
+```bash
+$ docker stack ps --no-trunc voting
+ID                          NAME                  IMAGE                                                                                                                 NODE   DESIRED STATE  CURREN STATE           ERROR  PORTS

+```
+
+### Only display task IDs
+
+The `-q ` or `--quiet` option only shows IDs of the tasks in the stack.
+This example outputs all task IDs of the "voting" stack;
+
+```bash
+$ docker stack ps -q voting
+xim5bcqtgk1b
+q7yik0ks1in6
+rx5yo0866nfx
+tz6j82jnwrx7
+w48spazhbmxc
+6jj1m02freg1
+kqgdmededccb
+t72q3z038jeh
+```
+
+This option can be used to perform batch operations. For example, you can use
+the task IDs as input for other commands, such as `docker inspect`. The
+following example inspects all tasks of the "voting" stack;
+
+```bash
+$ docker inspect $(docker stack ps -q voting)
+
+[
+    {
+        "ID": "xim5bcqtgk1b1gk0krq1",
+        "Version": {
+(...)
+```
