Need Help. What is the easiest to understand character sheet?

Hello All. I am currently working on my own custom Roll20 game by the name of Sketch-Venture in which I am making all of the assets: Map tiles, Character Tokens, Item pick-ups, basically everything I can. However, due to my peasant-like status of being a "Free" user, I can not make my own character sheet. This throws somewhat of a wrench in my original plans of creating an 'All Custom' game, as I was planning on making as simple of a sheet as I can so those not familiar with Table Top Games (TTGs) (Why did I just come up with an acronym? You guys are the ones who know plenty about this stuff, not me.) will be able to play it and so that it would be easily maintainable and manageable by me. So I must ask, What is the easiest to understand character sheet? I'm looking for something with the basic essentials(?) Such as stats, inventory, character info, and the few other important bits. Forgive me if I am over simplifying things, but I have next to no knowledge of how TTGs (Oh Gods kill me if I sound like an idiot.) work, so I wouldn't be asking for something like this if I didn't need it. Thank you all for spending you time reading and/or giving answers, apologizes for the inconvenience I may have caused. EDIT: Also, I am willing to learn how these sheets work, I'm not attempting to be lazy.

You can still build your character sheet. It just wont have the pretty html and css components. The core journal (character) has two tabs. The first one is the Bio & info tab which means it is just a big text field you can fill with basic text which is what we did when roll20 first started. I use to create my text sheet in that tab to represent what a paper sheet would have. The other tab is the Attributes & Abilities tab. The attribute column is where you name the attribute such as strength and put all your crunchy numbers in such as 18 (that would make it Strength 18). Abilities is where you can create macros (and make them token macros to boot) which would call on your attributes and such for dice rolls or whatever you would create for it would do. It boils down to the nuts and bolts that is the Attributes and Abilities tab while the character sheet tab (the html and css stuff) is the nice shiny shell that makes everything pretty and easier to input. It is not needed but it sure in the heck makes it easier.

Oh, Well thank you for that information Pat, That helps me very much. Well if anyone else knows of any shiny shells that are easy to understand be sure to post them here. I can work without them but it could be useful for other people.

For all the community created sheets, their codes are here in the  github . Usually there is a preview pic of them included in the files also.

Without being Pro, it will be VERY difficult to modify an existing sheet (usually the easiest method to learn how character sheets work) or to create a sheet outright. ;-( Also, on top of Pat's great advice, you can use the history feature of the github repo and see how a sheet may have evolved over time.  When character sheet's were first introduced to roll20, they were rather basic in their form and features.  Some sheets have change very little from their creation while others... Goodluck.

Alright then, thank you both for the help.
