user8134: I was surprised to learn that you can download and use Shredder for free. I was also surprised to learn that a GUI is required and needs to be downloaded separately. I was happy to learn that you can find some decent-looking chessboard GUIs for free on the internet. My question is: once I download Shredder and the appropriate GUI, what do I need to do to get them to work together?

user9081: Using GUI menu, you have to show engine filepath. Thats all.
Every GUI is different but there should be something like "add engine" where you can browse and select engine binary file.

user1943: Out of topic, but if you want free chess engine with ready UI and very powerful engine, I would reccommend you to use Stockfish.
