Getting good at 3rd strike


can anyone advise, or direct me to where or how i can get better at 3rd strike,
like some sort of guide or checklist to get better at this game, maybe even a guide to another street fighter but something comprehensive,
i cant really get past the basics, even on sfv i can seem to get to silver, i keep placing and practising but a step by step guide, maybe a syllabus of sorts, will be very helpful

thank you
