Can you also add the upgrade section part like this:

<a name='models'></a>
## Models
> Status: **changes required**
>
> Usage: [Models Documentation](db-models)
{: .alert .alert-info }

and also in the criteria document in the docs we will need an upgrade front matter tag the way we have it in filter for instance
