You can take a copy of the translation.json ( <a href="https://raw.githubusercontent.com/Cazra/roll20-cha" rel="nofollow">https://raw.githubusercontent.com/Cazra/roll20-cha</a>... ) and edit the text on the right (after the colon and in between the double quotes. do not change the format. ) into into Italian. ie "ATTACK": "Attacco", You'll probably need to work with the sheet author to test/verify that the translations are correct. Once it's good to go, your translated file (it.json) needs to be submitted (pull request made, sheet author or someone with github experience can do this for you.) and a new sub-folder for translations will need to be created within the sheet's main folder on the repo that will include all the specific language translations. This is normally handled by the repo manager. The other languages will simply be a copy of the english version until someone translates them as well.
