How to mods minecraft 1.8 on windows 7?

I have tried several tutorials none of which worked at all i've tried forge but it won't work. I have winrar please tell me a surefire way that will work. Remember its on minecraft 1.8 please help i've been tyrying for 3 days.

Forge doesn't get you mods! You have to use forge to RUN the mods, otherwise your game will crash and burn. Listen you need windows 10, TRUST ME It's better than 7. And, it's easier to get the mods.

Its a lot of hard work but look for a video its easier than reading it
