I've started a small wiki for me and my friends to have an archive for our RPG sessions but also so it can contain all sorts of stuff like factions, characters etc. Now I've created my first ever page and I've said to myself "Cool thing if I would have one of these Infoboxes things, right? Right!". Soon I've found out that the infobox has became greatest enemy on the field of being a Wiki Admin. I read some of the tutorials, but I am missing a point here. I understand so far that an Infobox is a template, it has certain parameters that need to be filled for order to appear on the page. What I don't get why I can't create my own template? How do I do it? Is there any easy way to just create a simple infobox. Like, four rows, a picture, a title and that's all. No funny stuff, no color changing, shape changing, and all that playing around. Just a simple, clean, nice infobox, so new people that visit can learn the general info about a character or a faction or a planet. Nothing else. You might call me the biggest idiot that has ever lived on the entirety of this planet, but I just don't know, and I don't think it should be a shame to admit to your lack of knowledge as long as you want to learn.
Thanks in advance for any help.
A total noob at infoboxes
