Further step for the porting instructions?

[philgyford]

Having just moved over to django-contrib-comments, I was really pleased that the instructions were so simple and it went so smoothly. Well done and thank you!

I had only one fatal error after following those instructions (using Django 1.7.4). I have an app that extends the comments app. The migration for this (there was only the 0001_initial.py migration) was like this:

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models, migrations

class Migration(migrations.Migration):

    dependencies = [
        ('comments', '__first__'),
    ]

    operations = [
        migrations.CreateModel(
            name='Annotation',
            fields=[
            ],
            options={
                'proxy': True,
            },
            bases=('comments.comment',),
        ),
    ]

When starting the server I got:

    ...
    File "/Users/phil/.virtualenvs/django-pepysdiary/lib/python2.7/site-packages/django/db/migrations/loader.py", line 169, in check_key
        raise ValueError("Dependency on unknown app: %s" % key[0])
ValueError: Dependency on unknown app: comments`.

Changing the two instances of comments to django_comments in the above migration seems to have fixed the problem (at least, the server runs; I haven't tried any migrations). I'm not sure if that's the best solution, or if it's worth mentioning this kind of thing in the instructions? What would be the best fix if I had a history of migration files that depended on the comments app?
