How to import Character Sheet

How can I import a new character sheet? I want to play runarcane (LOL RPG), but I don't know how to use this system in Roll20, so, if its possible, I would like to know how to import it. If have a tutorial to do it, I'll like to see it. Thanks Como faço pra importar uma nova ficha de personagem? Quero jogar o runarcana (rpg de lolzinho), mas não sei como usar o sistema no Roll20, então, se possível, gostaria de saber como importar a ficha pra cá. Se tiver um tutorial pra isso, gostaria de ver. Brigadão.

There isn’t a character sheet importer. Character sheets are written in HTML, CSS, JavaScript, etc.,  You need a Pro subscription to write and test a character sheet effectively.  There’s a thread in the Character Sheets & Compendium forum for requesting character sheets from the community who are writing them. 

If it's a simple enough system, you might not even need a character sheet. Many people play their games just using the Attributes and Abilities tab.
