If you only wanna do a full translation is more easy doing that with out the tk, translation is a big lsx file, you can edit that one with notepad++ or vscode and make a mod with the language folder you would wann to replace.
You would need multitool to search for the loca file and extrat that one, lslib to convert the file to lsx so you can edit it.
Check the discord if you need more info or help if you wanna do it with or with out the tk, theres channels for both modding methods.
