Need explaination with Mixin and MixinBooter

[Taskeren]

The template provides mixin options but not any document about it.

I added my mixin classes and set mixin packages to mixins.$modid.json, but it didn't work.
After I searched on many other projects using this template, I realize they all have a ILateMixinLoader or something, which is much different to modern Mixin loading and 1710 ones.

I want to know if we can have a document about how to setup mixins with this template, and a sample project will be even better.

I'll be explaining more over here in due time.

It would be better to have the link in template README when you finish it.
Nice work!
