+# Firebase Crash Reporting
+
+Firebase Crash Reporting is a free mobile crash analytics service. It provides
+detailed analytics and diagnostic information about the crashes encountered
+by your users. For more information about crash reporting and many other
+cool mobile services, check out [Firebase] (https://firebase.google.com).
+
+## Getting Started with Cocoapods
+
+1. Follow the instructions for
+ [setting up Firebase](https://developers.google.com/firebase/docs/ios/)
+2. Add the following to your Podfile
+
+ ```
+ pod 'Firebase/Crash'
+ ```
+
+3. Set up automatic symbol file uploads. Symbol files are required to
+ turn your stack traces into pretty classes and selectors. In
+ Xcode, click on your project file, choose your application target,
+ select "Build Phases", hit the little + sign to add a phase,
+ then select "Run Script". Fill the resulting build step with:
+
+ ```
+ "${PODS_ROOT}"/FirebaseCrash/upload-sym.sh
+ ```
+
+## Testing Integration
+
+In order to try out integration, you need to force a crash
+**while not attached to the debugger**. The debugger will
+intercept all crashes, preventing Firebase Crash Reporting from
+gathering any useful information.
+
+1. Add a crash somewhere in your app. This will do the trick:
+
+ ```
+ abort();
+ ```
+
+2. Run your app to get the latest code installed on the test
+ device, then once the app has launched, hit stop.
+
+3. Relaunch your app directly from the test device and trigger the crash.
+
+4. Restart your app (either in the debugger or not) and the crash will be
+ uploaded. Wait at least 10 seconds. Firebase Crash Reporting delays
+ crash uploading at startup to avoid creating contention with your own code.
+
+5. Your crash should show up in Firebase within 20 minutes.
+
+More information can be found in the
+[Firebase documentation](https://developers.google.com/firebase/).
+Happy bug hunting!
