+
+   SplashKit includes a CMake preset for generating code coverage reports using lcov. To use it:
+
+   ```sh
+   # Install lcov if you don't have it
+   brew install lcov
+
+   # Navigate to the cmake directory from the repository root
+   cd projects/cmake
+
+   # Configure the project with coverage flags
+   cmake --preset macOSCoverage -S .
+
+   # Build the project
+   cmake --build --preset macOSCoverage
+
+   # Run the tests to generate coverage data
+   cd ../../bin && ./skunit_tests
+
+   # Generate the coverage report
+   cd ..
+   lcov --capture --directory projects/cmake/build/macOSCoverage --output-file coverage.info --ignore-errors inconsistent,unsupported,format,count --include "/coresdk/src/coresdk/" --include "/coresdk/src/backend/"
+
+   # Create an HTML report
+   genhtml coverage.info --output-directory coverage_report --ignore-errors inconsistent,corrupt,unsupported,category
+
+   # Open the report
+   open coverage_report/index.html
+   ```
+
+   The report will show which parts of your code are covered by tests and which parts are not covered. This helps identify areas that need additional testing.
