You roll four six sided dice, and drop the lowest dice number of that roll, making a note of the result.

So if you rolled 3, 5, 6, and 4, you would drop 3, and then total the rest of the numbers, making a score of 15.

There are 6 abilities in total, meaning you have to do the above 6 times.

So at the end you would have 6 different numbers (so you might have 9, 18, 15, 4, 6, 7 as an example), you place each number onto an ability as you see fit (so you could put 18 on strength, 4 on wisdom, 7 on charisma until all the numbers have been used up.)
