Getting started with Reflect + Ditto

I’m wondering if somebody can direct me to some tutorials/guides (or even topics) regard the use of Reflect with Ditto. I’ve been Googling and searching around, but I can’t find much.

I’m just having some trouble getting started, and I’m a little confused about how I’m supposed to use Reflect and Ditto in conjunction.

All I really need to do is include an archive of posts in a sidebar on my pages that show blog posts. I understand Ditto fairly well, but Reflect is complicating things a little too much for me to guess my way around.

Thanks!
