+### Using Dice Rollers in Layouts
+
+> Note: The [Dice Roller](https://github.com/valentine195/obsidian-dice-roller) plugin must be installed and the [Use Dice Roller](#use-dice-roller) Setting must be turned on to use dice rollers in layouts.
+
+On any given block, if the Enable Dice property is turned on, the plugin will attempt to parse the property content for common dice roll strings. Currently, the plugin will parse for the following strings by default:
+
+1. Rolling to hit (`+15 to hit`)
+2. Damage / healing (`19 (2d10 + 8)`)
+3. A save (`Strength +5`) (note: the `saves` and `skillsaves` do not have dice enabled by default).
+
+Alternatively, you may specify a property of a monster to use as the dice string in the `Link Dice to Property` block property. This should be a dice string, such as `5d10 + 50`.
+
+#### Dice Callback
+
+If [Advanced Options](#show-advanced-options) is turned on, you also have the ability to provide a `Dice Callback` function to the block. This allows you to parse the property string for the *exact* dice roll you want.
+
+The callback function will receive the `plugin`, `monster` and `property` parameters.
