Getting Started with SonarCloud
When you first sign up for SonarCloud you have to choose which DevOps platform you want to connect to.
You then sign into SonarCloud with your existing credentials on that service (there is no such thing as a SonarCloud-only account). Your SonarCloud account is created and bound to your account on the DevOps platform.
At this point, you can import organizations from your DevOps platform to SonarCloud and then import repositories from those organizations. Each imported organization becomes a SonarCloud organization and each imported repository becomes a SonarCloud project. Once you import a project, it appears in your Projects list.
