Hey, if you go to the docs section there, it has an administrators guide, which is pretty good. I'd recommend you first test it with some filesystem. Flashcache is a little awkward to use at start since it stacks itself on top of your disk device. So you'll be mounting /dev/mapper/flashcache-something which consists of a flashcache device (the ssd, i.e. /dev/sdc) and a disk device (i.e. /dev/vg12/lvwebspace) There are various little obstacles to run into, thats why i don't know a good guide. But starting from the admin guide should help.

First off, what operating system is your server? The method to installation varies. With that said, have you looked at bcache? I find it to be superior: http://bcache.evilpiepirate.org/
