I'll also link something i have in my pockets, because _I want_ people to understand how brilliant and ahead of their time Lyotard and Baudrillard were (and talking about them as if they "injured" anything is nonsense). It's a 5-10 minute read, in english, and probably the best, shortest resource ever to understand postmodernism (it's kind of inaccurate though, but i don't want to nitpick when it's a 100 times better than what you read elsewhere):
