Getting into Nietzsche can be a bit confusing because of his way of expressing ideas. I think to start reading about this German philosopher can be with the following works.
1: On truth and falsehood in an extramoral sense.
2: The decline of the idols.
3: Thus Spake Zarathustra (his masterpiece)
Nietzsche is a rather pointed author, there is a Bulgarian film that talks a bit about his life, I highly recommend it. It's called "The day Nietzsche cried".
