UNLICENSED is used for non-open source projects

UNLICENSED is used for non-open source projects. Since README.md mentions that a project is free for anyone to use, I suggest changing the licence to MIT to make it true open source.
If you do not want to specify a license or if the source code is not open-source, please use the special value UNLICENSED. Note that UNLICENSED (no usage allowed, not present in SPDX license list) is different from UNLICENSE (grants all rights to everyone).
