Annotation to show Entity's property description - using nelmioapidocbundle - symfony

Question

I am using nelmioapidocbundle in order to documents my Rest API built on the top of symfony-2.x.
I can't found the right annotation to use to show each Entity's property description on the return section (Please see bellow attached image).
My Entity :
/**
* Checkins
*
* #ORM\Table(name="CheckIns")
* #ORM\Entity(repositoryClass="Project1\ApiBundle\Entity\CheckinsRepository")
*
* #ExclusionPolicy("none")
*/
class Checkins
{
/**
* #var integer
*
* #ORM\Column(name="id", type="bigint", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*
* #Groups({"checkin"})
* #
*/
private $id;
My Controller :
class CheckinController extends BaseRestController
{
/**
* #ApiDoc(
* resource=true,
* description="Find checkin by ID",
*
* parameters={
* {"name"="categoryId", "dataType"="integer", "required"=true, "description"="checkin id"}
* }
*
* output={
* "class"="Project1\ApiBundle\Entity\Checkins",
* "groups"={"checkin"}
* },
* statusCodes={
* 200="Checkin found",
* 400="ID is required",
* 404="Checkin not found"
* }
* )
*
* #Rest\View()
*/
public function getAction(Request $request)
{}
Result ( Description column is empty ) :

Answer 1

There's a description in doc section of the bundle:
For classes parsed with JMS metadata, description will be taken from the properties doc comment, if available.
For Form Types, you can add an extra option named description on each
field
