Help with NSMutable Dictionary

I've gone through the videos again and I can't figure out how to add elements from an array into an NSMutable Dictionary that has already been created. I get the general idea but I can't get the syntax right.

variable_assignment.mm 
NSArray *shoeOrder = @[@"Charles Smith", @(9.5), @"loafer", @"brown"];

NSMutableDictionary *shoeOrderDict = [[NSMutableDictionary alloc] init];

[shoeOrderDict setValue:@(shoeOrder objectAtIndex:0) forKey:@"name"];

Ok I've figured I probably need to use setObject: instead of setValue. But I'm still not sure how to add the objects from the shoeOrder array.
