How do I use my referral code?

Hello there, I'm curious about how I can utilize my referral code. Could you please walk me through the steps involved in sharing it with others and how they can benefit from it? Additionally, I'm wondering if there are any limitations or restrictions I should be aware of while using my referral code. It would be great if you could provide a clear and concise explanation, so I can understand the process better. Thank you in advance for your assistance.
