You can create your own Sets by adding set files to the
directory in the
CONFIG_DIR. A set file is a file where the
filename (no file extension) corresponds to the set name, and the
contents are a newline-separated list of mod atoms. Set files can also
include comments (lines starting with
# This is a list of mods gameplay-advancement/ncgd assets-meshes/rr-better-meshes
User sets with the same name as a builtin set will be ignored in favour of the builtin sets, as user sets have the lowest priority when loading.
