+# C++ Usage
+
+In certain scenarios, you may prefer direct access to SQLite C++ code, allowing efficient database operations directly from C++ in a React Native environment, independent of JavaScript.
+
+## Android CMake Integration
+
+The package supports prefab publishing for Android, which allows you to access it from within your CMakeLists.txt file.
+
+Add the following to your `CMakeLists.txt`:
+
+```cmake
+find_package(op-engineering_op-sqlite REQUIRED CONFIG)
+
+# Link all libraries together
+target_link_libraries(
+        ${PACKAGE_NAME}
+        ${LOG_LIB}
+        android
+        op-engineering_op-sqlite::op-sqlite
+)
+```
+
+## Header File Inclusion
+
+Due to platform differences, you need to include the SQLite header differently for Android and iOS:
+
+### Example on how to include the headers in C++
+
+```cpp
+#ifdef __ANDROID__
+#include <op-engineering_op-sqlite/sqlite3.h>
+#include <op-engineering_op-sqlite/bridge.h>
+#else
+#include <op-sqlite/sqlite3.h>
+#include <op-sqlite/bridge.h>
+#endif
+```
