The item format
The item format used is 'MaterialName:data' and can be set for multiple items with appending '-' in front and therefore using YAML lists.
Language (Non-English Users)
In the plugins/ucars directory there is a lang.yml file that ucars uses for all of it's messages sent to players. To modify them for your language, simply open the file and change the values. You can also download preconfigured language files on the language files page.
