User blog:MetalMickey272/Userboxes: Need Help Making

I just recently found the a template called Template:Userbox. Someone told me in the past that if I wanted to make a userbox, I use that. I was trying to make a userbox, but all the instructions wer confusing me. There was all these numbers and sizes and IDs and it really confused me, and I had no idea how to make a userbox using the template. I wanted to ask everyone on here if they could help me use this thing, and by help, I mean something alone the lines like explain what to do with template, like explain all the steps, or just tell me what to do with the template. I had a few in mind, and I wanted to make them, but can't with all of this confusion. Please, can someone tell me?
