How do I use this module? More documentation is required.

I'm having trouble understanding how to properly use this module, even after looking at the docs at http://skinr.org (I wouldn't call myself dumb although some people might disagree :)).

The documentation I'm referring to is more related to a site builder role. The developer doco is more complete.

For example, I have created a module that defines custom skins, and the skins are enabled ok.

What I want is, on one of my content types, to be able to click the skins link, select values for my 4 skins and save. These values must be different for each individual node.

I cannot find any documentation that details how to do this.

My skins have the correct theme hooks but when I click the skins link for a node I get an empty skins page asking me to add groups. This is not expected or well explained, coming from only ever using the old drupal 6 version.

Now for groups. "Groups" seems to be used to describe two different things, which is very confusing.

In the developer documentation, you set groups on skins. Like, default, layout etc. Makes sense.

Then in the UI though, you have to add a different kind of "Group".
Then when you add a group, you then get (within that new group) the other type of groups, that was previous defined in the skin code.
As you can see, this is confusing to even try to explain.

The group you create in the UI when you click the skins contextual link - What is this for and why do we need it?

The next issue is that once I add a group, which contains my options, I set values for the skins on a node, then I go to another node and it has the same settings. I want different settings for each node.

Basically, what I want for my admins to have is:
Click the contextual link for Skins and get my 4 options, which they can select values for and save.

What they currently get is:
Click the Skins contextual link, then get an odd page with a list of one group, and have to edit that to get to the actual settings. Then set values and save and end up back on the odd page and then have to go back out to view the node again.

This is not great UX for them.

Maybe I can make a custom contectual link that goes direct to the group I want them to edit.

I could be missing something very obvious or just be too tired but it all seems unnecessarily complex and confusing.
