You get a role in the beginning.
There is a certain number of bad guys, and good guys. Last game was 2 / 5.
In the day phase, the majority picks someone to lynch. In the night phase the bad guys can decide to take someone out. And each player can use his role accordingly. Game ends when either all bad guys are eliminated or enough good guys are gone, to not be able to take any bad guys out anymore.
Since almost all of us are noobs, you would be in good company. If ur still interested it is fun and a change to the seriousness of the situation in the country
