-#### GraphQL Code Generator's GraphQL-Request TypeScript Plugin
+### Get typed GraphQL Queries with GraphQL Code Generator
 
-A [GraphQL-Codegen plugin](https://graphql-code-generator.com/docs/plugins/typescript-graphql-request) that generates a `graphql-request` ready-to-use SDK, which is fully-typed.
+`graphql-request@^5` supports `TypedDocumentNode`, the typed counterpart of `graphql`'s `DocumentNode`.
+
+Installing and configuring [GraphQL Code Generator](https://www.the-guild.dev/graphql/codegen) requires a few steps in order to get end-to-end typed GraphQL operations using the provided `graphql()` helper:
+
+```ts
+import request from 'graphql-request';
+import { graphql } from './gql/gql';
+
+const getMovieQueryDocument = graphql(/* GraphQL */ `
+  query getMovie($title: String!) {
+    Movie(title: $title) {
+      releaseDate
+      actors {
+        name
+      }
+    }
+  }
+`);
+
+
+const data = await request(
+  'https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr',
+  getMovieQueryDocument,
+  // variables are type-checked!
+  { title: "Inception" }
+)
+
+// `data.Movie` is typed!
+```
+[_The complete example is available in the GraphQL Code Generator repository_](https://github.com/dotansimha/graphql-code-generator/tree/master/examples/front-end/react/graphql-request)
