Need a License file

There is no specified license file in this repo and none of the sources specify any copyright or licensing information.
Technically nobody can use these files since they are by default copyrighted to the original author which does not allow anybody else to use them without explicit permission from the author.
You really need to add a license file and updated the source files to to specify licensing and copyrights.

Review the repository's source files and existing project metadata to identify where licensing or copyright information is currently absent. Confirm the intended license and the complete set of files that should be updated; the work is done when the repository contains the agreed license file and the requested source-file notices.
