+### Optional Demangling
+
+KSCrash has an optional module that provides demangling for both C++ and Swift symbols: `DemangleFilter`. This module contains a KSCrash filter (`CrashReportFilterDemangle`) that can be used for demangling symbols in crash reports during the `sendAllReports` call *(if this filter is added to the filters pipeline)*.
+
+This module is used automatically if you use the `Installations` API. If you want to avoid demangling, you can set `isDemangleEnabled` in the `CrashInstallation` instance to `false`.
+
+If you don't use the `Installations` API, you can include this module manually:
+
+- With CocoaPods:
+  ```ruby
+  pod 'KSCrash/DemangleFilter'
+  ```
+
+- With SPM, add to your target dependencies:
+  ```swift
+  .product(name: "DemangleFilter", package: "KSCrash"),
+  ```
+
+The `CrashReportFilterDemangle` class also has a static API that you can use yourself in case you need to demangle a C++ or Swift symbol.
