Default CWM side load help

can somebody help me? rooted using the one click method on the forum and flashed CWM recovery, made a noob mistake and didn't put the new rom or gapps on my sd before hand and now im stuck in CWM recovery, it looks like I can sideload the roms but I don't know how to, I put my micro sd card in my laptop and put the roms on but CWM isn't mounting my sd card. thanks!
