+In order for Kosli to know where the scan results should be attested, certain parameters can be passed to the SonarScanner. Note that parameters cannot be passed with SonarCloud's Automatic Analysis - in this case, Kosli determines the relevant Flow and Trail as described below.
+
 These parameters can be passed to the scanner in three ways:
 - As part of the sonar-project.properties file used in CI analysis
 - As arguments to the scanner in your CI pipeline's YML file

 ## Testing the integration
 
 To test the webhook once configured, simply scan a project in SonarCloud or SonarQube. If successful, the results of the scan will be attested to the relevant Flow and Trail (and artifact, if applicable) as a sonar attestation. <br>
-If the webhook fails, check that you have passed the parameters to the scanner correctly, and that the flow name and artifact fingerprint are valid.

+## Alternatives:
+If you'd rather not use webhooks, or they don't quite fit your use-case, we also have a [CLI command](/client_reference/kosli_attest_sonar/) for attesting Sonar scan results to Kosli.
