# Mods

One of the core functionalities is our modding system. It allows us to make changes to your game files that without interfering with the original game files.

# Understanding the implications

Whenever our system makes a change to your game files, it will create a backup of the original file that is being modified. You can spot these backup files by their .original extension. If you want to modify a file manually, always check for the existence of a backup file. If it exists, do your changes in the original file since it will be used as a base for the system to recreate the modified file on your next restart.
Precaution: NEVER delete these files. The system will recreate them as if the latest modificated version of the file was the original one.
Remember: If you want to do manual changes to a file that is being modified by a mod, always do it in the original!
