+## 🧰 Player Settings
+
+For best results, BugSplat recommends building with the `IL2CPP` backend. The `Mono` backend is supported, but has several limitations. With `IL2CPP`, BugSplat can capture fully symbolicated C# exception traces in production, as well as native crashes that contain call stacks mapped back to their original C# function names, file names, and line numbers.
+
+To optimize your game for crash reporting, open `Player Settings` (`Edit > Player Settings`). Navigate to the `Configuration` section. For `Scripting Backend` choose `IL2CPP` and for `IL2CPP StackTrace Information` choose `Method Name, File Name, and Line Number`.

 ## ⚙️ Configuration
 
 BugSplat's Unity integration is flexible and can be used in various ways. The easiest way to get started is to attach the `BugSplatManager` Monobehaviour to a GameObject.

 ### Preventing Repeated Reports
 
-By default, BugSplat prevents reports from being sent at a rate greater than 1 per every 60 seconds. You can override the default crash report throttling implementation by setting `ShouldPostException` on your BugSplat instance. To override `ShouldPostException`, assign the property a new `Func<Exception, bool>` value. Be sure your new implementation can handle a null value for `Exception`!

 To enable the uploading of plugin symbols, generate an OAuth2 Client ID and Client Secret on the BugSplat [Integrations](https://app.bugsplat.com/v2/settings/database/integrations) page. Add your Client ID and Client Secret to the `BugSplatOptions` object you generated in the [Configuration](#⚙️-configuration) section. If your game contains Native Windows C++ plugins, `.dll` and `.pdb` files in the `Assets/Plugins/x86` and `Assets/Plugins/x86_64` folders will be uploaded by BugSplat's PostBuild script and used in symbolication.
 
+For IL2CPP builds, BugSplat will also upload `LineNumberMappings.json`. Line mappings allow BugSplat to replace generated C++ function names, file names, and line numbers with their original C# equivalents.

 ### Support Response
 
 BugSplat has the ability to display a support response to users who encounter a crash. You can show your users a generalized support response for all crashes, or a custom support response that corresponds to the type of crash that occurred. Defining a support response allows you to alert users that bug has been fixed in a new version, or that they need to update their graphics drivers.
