Close, but it works like this:
1. You import and enable the plugin and maybe play around with its plugin parameters like adding English, Chinese, etc.
2. You open your game
3. The plugin automatically extract/put all your game content to a spritesheet file (except text generated by other plugins).
4. You translate on this csv file or just play your game and open its own spreadsheet editor that will highlight the text that is being spoken
Your game players will be able to select the languages you setup.
