 For a game of [Dungeons & Dragons][dnd], each player starts by generating a character they can play with.
 This character has, among other things, six abilities; strength, dexterity, constitution, intelligence, wisdom and charisma.
 These six abilities have scores that are determined randomly.

 Your character's initial hitpoints are 10 + your character's constitution modifier.
 You find your character's constitution modifier by subtracting 10 from your character's constitution, divide by 2 and round down.

 Most programming languages feature (pseudo-)random generators, but few programming languages are designed to roll dice.
 One such language is [Troll][troll].

+# Introduction
+
+After weeks of anticipation, you and your friends get together for your very first game of [Dungeons & Dragons][dnd] (D&D).
+Since this is the first session of the game, each player has to generate a character to play with.
+The character's abilities are determined by rolling 6-sided dice, but where _are_ the dice?
+With a shock, you realize that your friends are waiting for _you_ to produce the dice; after all it was your idea to play D&D!
+Panicking, you realize you forgot to bring the dice, which would mean no D&D game.
+As you have some basic coding skills, you quickly come up with a solution: you'll write a program to simulate dice rolls.

+- 1 point for A
+- 3 points for B
