Sub VI Help

I was wondering if some one knows how to use SubVIs better than me. Every time I try to create a new SubVI it shows up in the project menu, which seems to be the way they were intended to work. But I want to use them to just clean up the program and make it easier to see. Could anyone point me in the right direction.

Thanks.

Does this help?
