-All effects within the Scala implementation are wrapped in `Sync` from [cats-effect][cats-effect]. In these examples we use `IO`, but anything that implements `Sync` can be used.
+You can provide wrappers for effects, such as `Sync`, `Eval` or `Id` from [cats-effect][cats-effect]. In the examples below we use `IO`.
