not a techie at all

hi there,

first of all, I’m not a techie so pls bear with me and 2nd, I’m also using sg optimizer but I always see that “add expires header” issue when I review my website speed and I’ve been looking for a plugin for that issue and this plugin seems to have the least amount of negative reviews so I’m thinking, this might be it!

just wanted to ask, is there a resource or article where, it tells a non-techie like me, what settings should I use for the this plugin? as to be honest, I cannot understand the things that are in the available, current resources. ?? it seems to complicated and technical for me.

I hope you can help, thanks in advance!
