Adding a License

[MrTreng]

Hi,

I noticed that your project does not have a license. This means it is not "open source" and prevents other people from forking and changing your project. In case this is an oversight rather than a conscious decision, I would like to suggest to have a look at the following website and choose an appropriate license: https://choosealicense.com/

Many thanks,
Treng
