 . Create a `sonar-project.properties` file to store your configuration
 .. Add a projectKey of your project
-.. Add a Build Wrapper output directory
 .. https://docs.sonarqube.org/latest/user-guide/user-token/[Generate a unique token] and set it as "sonar.login" (`SONARQUBE_TOKEN` in this example project)
 .. Set `sonar.host.url` to your SonarQube server URL
 . Download and unzip the Build Wrapper for macOS from {SonarQube URL}/static/cpp/build-wrapper-macosx-x86.zip
 . Add the Build Wrapper to your `$PATH`
 . Download and unzip the https://docs.sonarqube.org/latest/analysis/scan/sonarscanner/[SonarScanner] for macOS
 . Add the bin directory of the SonarScanner to your `$PATH`
-. Wrap your clean build command with the Build Wrapper. E.g.: `build-wrapper-macosx-x86 --out-dir bw-output xcodebuild clean build` (with `bw-output` being the same directory as the one set in `sonar-project.properties`)
-. Run `sonar-scanner`
+. Wrap your clean build command with the Build Wrapper. E.g.: `build-wrapper-macosx-x86 --out-dir bw-output xcodebuild clean build`
+. Run `sonar-scanner` specifying `-Dsonar.cfamily.compile-commands=bw-output/compile_commands.json` (with `bw-output` being the same directory as the one passed to Build Wrapper as `--out-dir`)
 
 You can take a look at the link:sonar-project.properties[sonar-project.properties] and link:build-analyze.sh[build-analyze.sh] (a script that downloads the `sonar-scanner` and the Build Wrapper before compiling and analyzing the project) to see it in practice. Please be aware that the SonarQube server URLs and the `sonar.login` are not completed in these examples.
