Resources (preferably free) for learning Hebrew?

So . . . I’ve been studying the Hebrew alphabet to start off with, which has been a lot easier than I initially figured. I’m taking it slowly and I’ve got up to dalet memorized. But I’m hoping people can recommend any helpful resources that they’ve used or know to be useful. There’s a lot of stuff out there but without a solid grounding in the language it’s hard to separate the good stuff from the junk.
