+## Auto Uploading Source Map Files
+
+For your app crashes to show up with a fully symbolicated stack trace, we will automatically generate the source map files and upload them to your dashboard on release build. To do so, we rely on your app token being explicitly added to `Instabug.startWithToken('YOUR_APP_TOKEN')` in JavaScript. 
+
+If your app token is defined as a constant or you have different tokens for both iOS and Android apps, set the token as shown below.
+
+1. In Android, go to the `build.gradle` file of the library and you will find below code, replace `YOUR_APP_TOKEN` with your app token from the dashboard.
+
+```java
+task upload_sourcemap(type: Exec) {
+    environment "INSTABUG_APP_TOKEN", "YOUR_APP_TOKEN"
+    commandLine 'sh', './upload_sourcemap.sh'
+}
+```
+
+2. In iOS, go to the build phases of the project, you will find a build phase called `Upload Sourcemap`. Expand it you will find below lines of code, replace `YOUR_APP_TOKEN` with your token from the dashboard.
+
+```bash
+export INSTABUG_APP_TOKEN="YOUR_APP_TOKEN"
+bash "../node_modules/instabug-reactnative/ios/upload_sourcemap.sh"
+```
