The contents of your modpack archive are in a subfolder called "mods". All the required folders (bin, config, mods) must be at the top level of the folder structure inside your archive.
Wait so I have to have Bin config and another mods folder inside my mods.zip folder?
I have Bin, config & a mods folder inside my modpack than I put my mods in the mod folder and my coremods in the coremod folder. after which I than put my mods in the mods folder into an archive called *mods* and the testing part I couldn't figure out how to get my modpack into vanilla minecraft I dropped my mods in the mod part and it didn't work. I probs sound really dumb but I've never made a modpack nore do I know how to test it. Any heads up on how to do that.
