Task could be doing 5, 10, 20, templates as different tasks.
For this task, you will be marking at least 5 templates for translation and importing their current translations.
You will be converting templates on commons.wikimedia.org to use the new /i18n subpage so that they are translatable with MediaWiki's Translate extension, which greatly improves translation workflow hence making coverage of translated docs vastly broader. You will also be importing the current translations into the new respective i18n subpage. However, you must not add new translations yourself, that's forbidden by the GCI rules.
