Hello everyone.

I just forked this and added my own 2 themes to my fork. Both themes are based on the winternord theme contained within that repository. In the theme the author, 2xx04 clearly states at the top that their code contains modifications to Bootstrap's CSS, as well as the Nord colour scheme by Arctic Ice Studio & Sven Greb. Both of those repositories contain the MIT license, but 2xx04's repository contains no license.

My question is this: Even though technically any github repository with no license has the default copyright rules applied to it (i.e. the author has sole ownership), since they failed to include the license of the software they modified, my repository should include the MIT license, and any code written by me is mine (under MIT license rules of course, so anyone can copy and distribute it)?

Thanks in advance. Here is a link to my repository in case you need it to understand what I mean
