Dota 2 is a game that demands a lot of hours for a player to play at a decent level via the Dota 2 Matchmaking system. To serve the growing number of players trying out Dota 2, Valve has released in-game tutorials aimed at players with zero real-time strategy experience.
New players are taught the Dota 2 basics via the Dota2 tutorial
These tutorials start with teaching basic character movement and Dota mechanics and go on to the Limited Hero mode where a new player can play with other humans as they learn the complex game of Dota 2 together.
To assist new players, the Neutral Creeps have made a Dota 2 guide for the Dota 2 training maps.

While the tutorials teach some basic knowledge about Dota, the best teacher for Dota 2 (outside of Mentors) is experience. Each game of Dota 2 always gives people something to learn about the game and there are always new things being discovered.
While the game is played at a competitive level, we recommend learning it at your own pace and to just enjoy the beautiful fantasy world of Dota 2.
