+directive @void on FIELD_DEFINITION
+```
+
+To enable this directive, add the service provider to your `config/app.php`:
+
+```php
+'providers' => [
+    \Nuwave\Lighthouse\Void\VoidServiceProvider::class,
+],
+```
+
+Lighthouse will register the following type in your schema:
+
+```graphql
+"""
+Allows only one value and thus can hold no information.
+
+https://en.wikipedia.org/wiki/Unit_type
+"""
+enum Unit {
+  "The only possible value."
+  UNIT
+}
+```
+
+Use this directive on mutations that return no value, see [motivation](https://github.com/graphql/graphql-spec/issues/906).
+
+```graphql
+type Mutation {
+  fireAndForget: _ @void
+}
+```
+
+Lighthouse will modify the definition of your field and have it return `Unit!`.
+No matter what your resolver returns, the resulting value will always be `UNIT`.
