Build order and plan for forward barracks push

Hey guys! I think it is one of the build orders that I don't know or its hard for me to learn. How to execute the forward barracks push accompanied by archery range. What is the build order and what is the plan after I go forward, go spears and skirms? But they won't kill vills, right? And my base will be unprotected too. Sorry for putting forward too much questions about the forward push(lol). I would be so happy to hear from you guys! Thanks for your time :)
