Documentation for adding custom group type

Hi.

I was wondering if documentation exists for creating a custom group type in open social? There are multiple areas you need to add the custom group type. For instance in many views, or is there an easier way doing this?

For example in the group_events view, the "CONTEXTUAL FILTERS" -> "Group content: Parent group" where you will need to add your custom group type.

Also adding a custom group to the "$group->bundle()" array, which I have not figured out yet.

Thanks!
