+#### Configure
+
+Add the following to your SDK config. There are several privacy and sampling options available, all of which can be set using the `integrations` constructor. Learn more about configuring Session Replay by reading the [configuration docs](https://docs.sentry.io/platforms/javascript/session-replay/).
+
+```javascript
+import * as Sentry from "@sentry/electron";
+
+Sentry.init({
+  dsn: "___PUBLIC_DSN___",
+
+  // This sets the sample rate to be 10%. You may want this to be 100% while
+  // in development and sample at a lower rate in production
+  replaysSessionSampleRate: 0.1,
+  // If the entire session is not sampled, use the below sample rate to sample
+  // sessions when an error occurs.
+  replaysOnErrorSampleRate: 1.0,
+
+  integrations: [new Sentry.Replay()],
+});
+```
