+# @grafana/instrumentation-fetch
+
+Faro instrumentation of the JavaScript [Fetch](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) API.
+
+❗️*Warning*: this package is experimental and may be subject to frequent and breaking changes.
+Use at your own risk.❗️
+
+## Installation and Usage
+
+❗️*Warning*: This package is not interoperable with `@opentelemetry/instrumentation-fetch`.
+Use one or the other❗️
+
+Add the instrumentation as outlined below.
+The instrumentation send the following events alongside respective request/response data like HTTP
+headers and other response properties like status codes the requests url and more.
+
+Event names are:
+
+- `faro.fetch.resolved` for resolved requests.
+- `faro.fetch.rejected` for rejected requests.
+
+```ts
+// index.ts
+import { FetchInstrumentation } from '@grafana/faro-instrumentation-fetch';
+import { getWebInstrumentations, initializeFaro } from '@grafana/faro-react';
+
+initializeFaro({
+  // ...
+  instrumentations: [
+    // Load the default Web instrumentations
+    ...getWebInstrumentations(),
+    // Add fetch instrumentation
+    new FetchInstrumentation(),
+  ],
+});
+
+
+// myApi.ts
+fetch(...) // Use fetch as normal - telemetry data is sent to your Faro endpoint
+```
+
+## Backend correlation
+
+In order to prepare backend correlation, this instrumentation adds the following headers to each
+request that server-side instrumentation can use as context:
+
+- `x-faro-session` - the client-side session id
+
+## Planned Development
+
+- Additional functionality to correlate frontend requests with backend actions
+- Event attributes with end-to-end timing details
