Do some research and reading first. Think about what you're asking. Even if "Lucifer" is a label for a certain type of energy, rather than an actual entity, without a proper background and knowledge to know what you're doing, you could literally ruin your life. If you want to call Lucifer because you want to do something against someone else, keep karma in mind (ya, I know many don't believe in that, but why not be safe rather than sorry).
Not the answer most people want to hear, but this is like when someone asks me "How do I configure a port forward on Cisco router?". Well, you don't have any basic knowledge (subnetting, security, etc), so sure I could tell you, but how would you ever know if you were doing things safely and securely without the pre-requisite knowledge? It might work. It might also open your entire location to hackers. There is no substitute for having as much information and experience as possible.
Too many people want to skip step 1 through 10, and go directly to step 50. It's dangerous, from an emotional/mental standpoint at least.
Start smaller, since you're a beginner. Pick a path and do some research and some basic rituals. Get familiar with the process first.
