+### Unchecked scalars input
+
+GraphQL does not support input unions, hence it's not possible to support both normal inputs and unchecked scalars input at the same time like the Prisma does.
+
+If you prefer simplicity over more sophisticated solutions like `connectOrCreate`, you can to provide the `useUncheckedScalarInputs` generator option:
+
+```prisma
+generator typegraphql {
+  provider                 = "typegraphql-prisma"
+  output                   = "../prisma/generated/type-graphql"
+  useUncheckedScalarInputs = true
+}
+```
+
+This way there will be generate input classes with relation id fields, instead of the normal "nested" inputs for creating/updating relations, e.g.:
+
+```ts
+@TypeGraphQL.InputType({
+  isAbstract: true,
+})
+export class PostUncheckedCreateInput {
+  @TypeGraphQL.Field(_type => String, {
+    nullable: false,
+  })
+  title!: string;
+
+  @TypeGraphQL.Field(_type => TypeGraphQL.Int, {
+    nullable: false,
+  })
+  authorId!: number;
+
+  @TypeGraphQL.Field(_type => TypeGraphQL.Int, {
+    nullable: true,
+  })
+  editorId?: number | undefined;
+}
+```
+
 ### Nest JS
 
 In order to use generated types and resolvers classes in NestJS, you need to use the [official `typegraphql-nestjs` package](https://github.com/MichalLytek/typegraphql-nestjs). This module allows for basic integration of TypeGraphQL with NestJS. You can find an example in the [`examples/4-nest-js` folder](https://github.com/MichalLytek/typegraphql-prisma/tree/main/examples/4-nest-js).
