If you would like to contribute translations, fork the repository, copy
en.json in the localization folder, translate the values (leave
the keys intact), and open a pull request. For an example, see the French
translation in fr.json. Note that changing the names of the channels
means you will need to run !server_setup so that the bot can generate
channels with the correct names and permissions.
You can also submit translations of the cards used in the game by copying the
templates folder in resources/images and matching the new folder name to
the key used for the language, then editing the .kra file and exporting the
translated cards AS PNG FILES. The bot will default to the English
versions of any cards it can't find. To edit the files, you will need
Krita, an open source tool for creating and modifying
images. Not all of the cards currently have templates,
so feel free to submit those as well!
