Adding model-wide help text to a django model's admin form

In my django app, I would like to be able to add customized help text to the admin change form for some of my models. Note I'm not talking about the field specific help_text attribute that I can set on individual fields. For example, at the top of the change form for My_Model in My_App I'd like to be able to add some HTML that says "For additional information about My Model, see http://example.com" in order to provide a link to an internal documentation wiki.

Is there any simple way of accomplishing this, or do I need to create a custom admin form for the model? If so, can you give me an example of how I would do that?

Since django 3.0 it's now possible to override the help_text of admin fields more easily:

from django.utils.translation import gettext_lazy as _

class AuthorForm(ModelForm):
    class Meta:
        model = Author
        fields = ('name', 'title', 'birth_date')
        labels = {
            'name': _('Writer'),
        }
        help_texts = {
            'name': _('Some useful help text.'),
        }
        error_messages = {
            'name': {
                'max_length': _("This writer's name is too long."),
            },
        }
