-## Preparation
+## Update Router
 
-Follow Cloudflare's [Migration Guide](https://developers.cloudflare.com/workers/wrangler/migration/migrating-from-wrangler-1/) to update your protject to [wrangler2](https://github.com/cloudflare/wrangler2).
-
-## Update
-
-Update to the latest version verstion
+Update to the latest version version of the router.
 
 ```bash
 npm i -D @tsndr/cloudflare-worker-router
 ```
 
-## Import / Require
 
-Switch to ESModules.
+## Handlers
+
+- Remove `res` and `next` from handler parameter list.
+- Replace `res.` with `return new Response()` / `return Response.json()`.
+- Remove `next()` calls from middlewares.
+
 
 ### Before
 
-```javascript
-const Router = require('@tsndr/cloudflare-worker-router')
+```typescript
+// Register global middleware
+router.use(({ env, req, res, next }) => {
+    if (req.headers.get('authorization') !== env.SECRET_TOKEN) {
+        res.status = 401
+        return

+    res.body = {
+        id: 1,
+        name: 'John Doe'
+    }
+})
 ```
 
 
 ### After
 
-```javascript
-import Router from '@tsndr/cloudflare-worker-router'
+```typescript
+// Register global middleware
+router.use(({ env, req }) => {
+    // Intercept if token doesn't match
