-2. [Encrypt this token](/user/encryption-keys/#usage) `travis encrypt abcdef0123456789` or define `SONAR_TOKEN` in your [Repository Settings](/user/environment-variables/#defining-variables-in-repository-settings)
-3. [Find which SonarCloud.io organization](https://sonarcloud.io/account/organizations) you want to push your project on and get its key
-4. Create a `sonar-project.properties` file for your project (see the [documentation](http://redirect.sonarsource.com/doc/install-configure-scanner.html)).
