Ok, I did some research, to find how I can translate the sheet. I understood that I have to create a github account, and then work on the original "A song of ice and fire" sheet file, which is located here : <a href="https://github.com/Roll20/roll20-character-sheets/blob/master/A%20Song%20of%20Ice%20and%20Fire/SIFRPNew.html" rel="nofollow">https://github.com/Roll20/roll20-character-sheets/blob/master/A%20Song%20of%20Ice%20and%20Fire/SIFRPNew.html</a> I tried to get an example from another sheet already translated, but the code is not exactly the same. Just so you know, I'm not much of a coder ^^ Just trying to figure out how it works. So, I need to create a global " translation.json " file, then create a new folder " translation ", and put my French translation in it. But actually, it seems that the original code is not any " data-i18n " in its code. But it seems there's always some of it in other sheets codes. Can someone please help me about that please ?
