About the LICENSE

[wholesomemoon]

Hello, first of all, thank you for opening this wonderful code.
I'm considering about using this feature/descriptor module(both extraction and matching) in my iOS project. However I first need to check the LICENSE of this repository before testing the module's performance and adding it as a dependency framework. So I'd be grateful if you could let me know whether you have any plans of specifying the LICENSE explicitly in the repository.
Thank you for your kind work again.
