In short Magic the Gathering(MTG) is a trading card game. As you play you accumulate a collection of cards that you use to build a deck. You use your deck to play a game of Magic against one or more people. Within Magic there are many different variations also know as formats that people enjoy. This website is all about the pauper format but other popular formats include Standard, Modern, and Commander EDH. Magic is a very complicated game with things that happen that and can't be fully learned from reading these pages or watching videos. After understanding the basics the only way to learn is by doing. You can play Magic in either paper or on one of three online platforms. For paper play you can find a local game store(LGS) and go play at Friday Night Magic(FNM) events. To play online there is MTGO, Magic the Gathering Arena, and Magic Duels. The next few pages are there to help comprehend the game of Magic in a basic form to help new players learn. I hope it help.
I recommend watching the official video to get a basic overview of the game and visual examples to go along with it and then for a more in depth understanding read through the pages on this website.
