lets talk film

so i have a nikkormat el. i got it from kevin's step dad, kirk. its pretty swanky. i wanna learn how to use it. the only problem is i cannot for the life of me figure out how to open it to put the film in. i know, i'm a genius, but seriously i've pushed and pulled and tried everything i can think of. so my last resort is to get online and figure it out, because if you can't find it online, it doesn't exists.
