   well-meant, but in both cases mtime based cache modes can be problematic.
 
+The ``--files-changed`` option controls how Borg detects if a file has changed during backup:
+ - ctime (default): Use ctime to detect changes. This is the safest option.
+ - mtime: Use mtime to detect changes.
+ - disabled: Disable the "file has changed while we backed it up" detection completely.
+   This is not recommended unless you know what you're doing, as it could lead to
+   inconsistent backups if files change during the backup process.
+
 The mount points of filesystems or filesystem snapshots should be the same for every
 creation of a new archive to ensure fast operation. This is because the file cache that
 is used to determine changed files quickly uses absolute filenames.
