 ### Batching
 
 It is possible with `graphql-request` to use [batching](https://github.com/graphql/graphql-over-http/blob/main/rfcs/Batching.md) via the `batchRequests()` function. Example available at [examples/batching-requests.ts](examples/batching-requests.ts)

 You can define the `signal` in the `GraphQLClient` constructor:
 
 ```ts

+const abortController = new AbortController()
 
-  const client = new GraphQLClient(endpoint, { signal: abortController.signal })

 You can also set the signal per request (this will override an existing GraphQLClient signal):
 
 ```ts
-  const abortController = new AbortController()
+const abortController = new AbortController()
 
-  const client = new GraphQLClient(endpoint)
-  client.request({ document: query, signal: abortController.signal })
+const client = new GraphQLClient(endpoint)

-  abortController.abort()
+abortController.abort()
 ```
 
 In Node environment, `AbortController` is supported since version v14.17.0.
 For Node.js v12 you can use [abort-controller](https://github.com/mysticatea/abort-controller) polyfill.

  import 'abort-controller/polyfill'

 ### Middleware
 
 It's possible to use a middleware to pre-process any request or handle raw response.
 
 Request middleware example (set actual auth token to each request):
+
 ```ts
 function middleware(request: RequestInit) {
-  const token = getToken();
+  const token = getToken()
   return {
     ...request,
     headers: { ...request.headers, 'x-auth-token': token },

+By default GraphQLClient will throw when an error is received. However, sometimes you still want to resolve the (partial) data you received.
 You can define `errorPolicy` in the `GraphQLClient` constructor.
 
 ```ts
-const client = new GraphQLClient(endpoint, {errorPolicy: "all"});

 #### None (default)
+
 Allow no errors at all. If you receive a GraphQL error the client will throw.
 
 #### Ignore
+
 Ignore incoming errors and resolve like no errors occurred
 
 #### All
+
 Return both the errors and data, only works with `rawRequest`.
