The overlay is situated here: https://github.com/mradermaxlol/maxik-ebuilds All ebuilds are using EAPI 6, all the features provided by them work. The only enhancement that can be made is metadata.xml files for USE flags descriptions.
After looking at https://blog.hartwork.org/?p=843 , I'm thinking of changing the overlay name, or is it OK now? Description is like "Ebuilds for various software with minor enhancements", the owner is <mrader3940@opmbx.org> aka me. I'm not sure about the SSH key... What exactly do I need to do about it?
I've made a key at GitHub. What should I do with it?
Closing, will create another bug with proper info.
