 ## Rolling dice from code
 
-To roll dice in code, use the `roll` function from this module. It has two
-main ways to define the expected roll:
-
-```python
-from evennia.contrib.rpg.dice import roll
-
-roll(dice, dicetype=6, modifier=None, conditional=None, return_tuple=False,
-      max_dicenum=10, max_dicetype=1000)
-
-```
-
-You can only roll one set of dice. If your RPG requires you to roll multiple
-sets of dice and combine them in more advanced ways, you can do so with multiple
-`roll()` calls.
-
-### Roll dice based on a string
-
 You can specify the first argument as a string on standard RPG d-syntax (NdM,
 where N is the number of dice to roll, and M is the number sides per dice):
 
 ```python
+from evennia.contrib.rpg.dice import roll
+
 roll("3d10 + 2")
 ```

 ```
 
-### Explicit arguments
-
 If you specify the first argument as an integer, it's interpret as the number of
 dice to roll and you can then build the roll more explicitly. This can be
 useful if you are using the roller together with some other system and want to
 construct the roll from components.
