 You can define custom category files for ChestSort using simple .txt files.
+
 If you have {category} in your sorting-method, it will get replaced with the category name.
+
 Category names are determined by the file names. The name must start with a number ranging
 from 000 to 899 and end with .txt
+
 Default categories are prefixed with 900 to 999. Please do not edit the default categories.
 You can instead copy or rename the default files and edit those instead.
+WARNING: All files with names starting between 900 and 999 will be deleted on start.
+
 If you put {keepCategoryOrder} behind {category} in the sorting-method, the items will be
 ordered exactly as listed in the category files. Otherwise, they will be grouped by category
 and then sorted according to the remaining variables in your sorting-method.
+
 Category files can contain asterisks (*) as wildcard character at the beginning and/or end
 of an expression, but not in the middle.
+
 Category files can also contain comments using the hashtag (#) symbol
