+### Custom IPC Namespace
+
+If your Electron application uses multiple IPC channels and you want to prevent potential conflicts between them, you can specify a custom namespace for the IPC channels used by Sentry with the `ipcNamespace` option.
+
+To use a custom namespace, you need to configure it in all three contexts: main process, renderer processes, and preload scripts.
+
+**In the main process:**
+
+```javascript
+import * as Sentry from "@sentry/electron/main";
+
+Sentry.init({
+  dsn: "___PUBLIC_DSN___",
+  ipcNamespace: "some-app",
+});
+```
+
+**In renderer processes:**
+
+```javascript
+import * as Sentry from '@sentry/electron/renderer';
+
+Sentry.init({
+  ipcNamespace: 'some-app',
+});
+```
+
+**In preload scripts:**
+
+```javascript
+import { hookupIpc } from '@sentry/electron/preload-namespaced';
+
+hookupIpc('some-app');
+```
+
+When set, the IPC channels used by Sentry will be prefixed with the specified namespace (e.g., `some-app`), helping to avoid conflicts with other IPC channels in your application. Make sure to use the same namespace value across all processes for proper communication.
+
+For more configuration options, see the <PlatformLink to="/configuration/options/#ipcNamespace">configuration options documentation</PlatformLink>.

 ### Preload Injection
 
 The SDK attempts to inject a preload script via [`session.setPreloads(preloads)`](https://www.electronjs.org/docs/latest/api/session#sessetpreloadspreloads) and by default only does this for the `defaultSession`. If you are using other sessions, you can pass custom sessions via the `getSessions` option in the `main` process:
