+### Setting Up the Service Worker
+
+To ensure event capturing works correctly, you need to set up the service worker. Create a file named `sw.js` and add the following code:
+
+```javascript
+let events = []
+
+self.addEventListener('install', (event) => {
+  console.log('Service Worker installed')
+  event.waitUntil(self.skipWaiting())
+})
+
+self.addEventListener('activate', (event) => {
+  console.log('Service Worker activated')
+  event.waitUntil(self.clients.claim())
+})
+
+self.addEventListener('message', (event) => {
+  if (event.data.type === 'LOG_EVENT') {
+    const newEvent = {
+      eventName: event.data.eventName,
+      eventData: event.data.eventData,
+      timestamp: new Date().toISOString(),
+    }
+    events.push(newEvent)
+
+    if (events.length > 100) {
+      events.shift()
+    }
+  }
+
+  if (event.data.type === 'GET_EVENTS') {
+    event.source.postMessage({ type: 'EVENTS_LIST', events })
+  }
+
+  if (event.data.type === 'CLEAR_EVENTS') {
+    events = []
+    event.source.postMessage({ type: 'EVENTS_CLEARED' })
+  }
+})
+```
+
+#### Where to Place the File
+
+Place the `sw.js` file at the root of your project. Make sure to register it correctly using the code shown in the Basic Setup section to ensure the service worker is active and ready to capture events.
