Oh boy, where to start... I've spent most of my free time over the last year answering this question for myself ;)
You can get the basics of puts and calls off Wikipedia, but it takes a while to get the intuition down, understand spreads, etc. This just comes with research and practice. But understanding the instrument and profitably trading are two totally different things.
To understand at a philosophical level why and a bit of how (generally long, not short), I highly recommend Antifragile by Nassim Taleb. It has simultaneously everything and nothing to do with options trading. Armed with the basics of puts and calls though, you can infer what he's doing.
Next, I would recommend starting reading his book Dynamic Hedging, which is a proper technical work on options that is actually surprisingly approachable. He gets deep in the weeds, but I promise it's worth it if you're serious about this. You don't need to finish the book before making your first trade (I'm still in progress; about 25% through).
There are also of course a number of RV videos I found off the hook awesome. Watch these as soon as you understand the basics of puts and calls, and have some intuition of what delta, gamma, and theta are. Then re-watch them again after a few months of study and your mind will be blown.

Finally, I'd also recommend Chapter 3 and all of Part VII of Statistical Consequences of Fat Tails (available free: https://arxiv.org/abs/2001.1048842). It covers some of the math of the distributions, risk, hedging, etc. in a lot of depth (requires basic Calculus in some parts). This tends to be a bit more theoretical than about the practicalities of trading, but I found it worthwhile.
Hope this helps!
