How to make guide layers for pose copier

So I am going to try and use the pose copier for the first time, and have watched the webinar, but she lost me when she started talking about guide layers.

In the video the presenter indicates that these layers don’t actually contain any drawings, and they are essentially links to frames in the template. All good, but there ARE drawings indicated in the timeline that link to the drawing elements that are included in the pose copier template somehow.

I am completely confused how to make these guide layers, and it skips over them in the online documentation. So this cant be a difficult process Im thinking?

Can someone please let me know how to make these guide layers for the pose copier?

Thanks for your help!
