https://www.reddit.com/user/Ok-Control-787/ gave really great advice in his comment. The only thing I would even consider adding is that there's an awesome book called "Logical Chess Move by Move".
On Amazon, the free preview gives you the first three games (out of like 82), where the author talks about literally every move, and why you play it. Even having just those eight games is a great resource, but you probably need to spend 15-20 minutes going through each game.
Here's the link:

Everything you wanted to know about openings, until you're 1500 or so, is on Wikipedia.

Here's another one:
I don't know 100% if this link will work from outside Canada. What I did was go to Amazon, look up "Logical Chess Move by Move" by Irving Chernev. There are a couple of editions, and all offer a preview of the book. The edition with the Black cover and two knights face to face offers you a preview that gives you eight fully annotated gaves, every move.
In my opinion, this is the best book for anybody who has learned what a fork or a pin is, but doesn't know much else. It is a thorough tutorial on the principles behind opening play. Going through the first eight games, available free, entirely legally, via the preview for this edition, will get you very far on your way.
