Question: How can I add description

Should I be adding description to meta class of DjangoObjectType?

Update:

Adding description to meta class of DjangoObjectType did not do anything.

What about description for model fields?
How can I attach description for the fields of ChannelNode (name, customer etc…)?

Can you provide a code snippet? Here is a working example of mine :

class ChannelNode(DjangoObjectType):
    class Meta:
        model = Channel
        filter_fields = {'name': ['exact', 'icontains', 'istartswith'],
                         'customer': ['exact', 'icontains', 'istartswith']}
        interfaces = (relay.Node,)
        description = "This is a Channel Node"

If you navigate on ChannelNode on the GraphiQl you will see the description.
