+# Using with Fastlane 🚀
+
+If you already use Fastlane, you can simply setup a new lane performing the analysis as follows:
+
+```ruby
+lane :metrics do
+    scan(scheme: "[SCHEME]", code_coverage: true, output_directory: "./reports")
+    slather(cobertura_xml: true, scheme: "[SCHEME]", output_directory: "./reports", proj: "./[PROJECT].xcodeproj")
+    sh("cd .. && lizard ./[SOURCE_FOLDER] -l swift --xml > ./reports/lizard-report.xml")
+    swiftlint(output_file: "./reports/swiftlint.txt", ignore_exit_status: true)
+    sonar
+end
+
+```
+
+## Options
+
+Fastlane's `sonar` action allows you to define or override a number of SonarQube properties, such as `sonar.project-version`.
+
+For instance:
+
+```ruby
+  sonar(project_version: "1.0b")
+```
+
+You can read the complete documentation of Fastlane's `sonar` action on your terminal via:
+
+```bash
+  fastlane action sonar
+```
+
+## `sonar-project.properties`
+
+Please note that, in order to have your analysis performed via the tools above, you'll need to setup your `sonar-project.properties` file accordingly, as per the following example.
+
+```
+sonar.junit.reportsPath=reports/
+sonar.junit.include=*.junit
+sonar.swift.lizard.report=reports/lizard-report.xml
+sonar.swift.coverage.reportPattern=reports/cobertura.xml
+sonar.swift.swiftlint.report=reports/*swiftlint.txt
+```
