 _The following examples assume you are using Remix. They will be updated when Superflare supports other frameworks._
 
-To create a `SuperflareSession` instance, pass a valid `Session` instance:
+The `@superflare/remix` package exports `handleFetch`, which takes care of session creation and makes the session available on your Remix `AppContext`. In your main worker file, you import and use the utility like so:
 
 ```ts
 // worker.ts
 
-import { SuperflareSession } from "superflare";
-
-// Create a Remix `session`...
-const session = "...";
-
-const superflareSession = new SuperflareSession(session);
-```
-
-Then, you can inject the session into your Remix `loadContext`:
-
-```ts
-// worker.ts
-
-const loadContext = { session, env };
-
-try {
-  const config = getConfig({ request, env, ctx });
-
-  return handleFetch(
-    {
-      config,
-      session,
-      getSessionCookie: () =>
-        sessionStorage.commitSession(session.getSession()),
-    },
-    () => remixHandler(request, loadContext)
-  );
-} catch (error) {
-  return new Response("Internal Server Error", { status: 500 });
-}
+import { createRequestHandler, type ServerBuild } from "@remix-run/cloudflare";
+import { handleFetch } from "@superflare/remix";
+import config from "./superflare.config";
+
+const handleRequest = createRequestHandler(build as any as ServerBuild);
+
+export default {
+  async fetch(request, env, ctx) {
+    try {
+      return await handleFetch<Env>(request, env, ctx, config, handleRequest);
+    } catch (error) {
+      console.log(error);
+      return new Response("An unexpected error occurred", { status: 500 });
