 Take your [Replacer Slots](#replacer-slots-or-ireplacerslotquestion) `__replacerSlot__`, the [Case Converters](#case-converters) `PascalCase__` and combine them together to make `__replacerSlot__PascalCase__`.
 
 One Rule: no spaces between the [Replacer Slots](#replacer-slots-or-ireplacerslotquestion) and [Case Converters](#case-converters). If there is a space, [Case Converters](#case-converters) will not work.
