We're all here to help each other, and there are a lot of people in the forum who can give step-by-step instructions on networking, including me, but it's a good idea to make some effort yourself first. Giving detailed instructions from the beginning every time someone asks for it is not practicable. It can be a long tedious process. Demanding such spoon feeding may also be considered rude.
Search the internet. There must be many websites on the subject. Maybe someone has already given a tutorial in the Tutorials section here. Learn as much as you can by yourself. Then, if there's something you cannot understand, ask here.
