Looking for resources to learn Interslavic as someone who speaks a slavic language
So I really want to learn interslavic, but whenever I look for courses they're always seemingly intended for those who don't know slavic languages at all. I don't think learning vocabulary words is particularly beneficial for me. I guess my question is are there any simple texts anyone can recommend, or maybe tips on how to learn it effectively? Resources on grammar, conjugation, and sentence structure would be helpful as well
