Minecraft Flans Mod install (does not work)?

I can't install the Flans mod. I have Forge for the same version and all, but whenever I drag the Flans mod file into the mods folder it does not work.

What does not work?

You have to mod in the mods folder
you go into the general directory of minecraft and create there a folder called flan and there you have to then make the flan packs you want to have
when you're done with all the games start and treat

The mod folder in the mods folder of minecraft to draw when I do it and minecraft start there's no mod
