Running node for Beginner

Hello everyone, I’m quite new to the concept of running nodes and would like to delve into it. However, I find myself needing assistance. Could anyone provide a detailed, step-by-step guide on how to set up and run a node, starting from purchasing a server to the actual operation? I’ve attempted to read through the documentation, but it feels a bit too advanced for me at the moment. I appreciate any help you can offer. Thank you!
