To start, all you need to know is that Hearthstone is a two player card game where the goal is to get the opponents health down to zero. Players take turns to play cards that represent things like casting spells and putting minions on the board. All cards are different from one another, but you don't have to memorize them to play the game as the function of each card and its cost is described on the card itself. Most of the game's mechanics such as card draws, mana distribution and action order are automated. You just have to focus on playing the cards in your hand in the best order possible. That's it.
While the mechanics are straightforward they allow for wildly different situations to be created on the board. And the more you know about the game the more ways you'll find of creating situations that benefit you. Add to that an ever expanding list of cards and the ability to customize your deck and you can have stuff to delve into for ages.
