Creating and managing a community
This section will cover how to create and manage a community. We will also learn about the different community templates. We will then learn about the self-registration option. We'll see how to configure a community and see a community in action with self-registration.
Before starting to create a community, make sure your org has at least one community license (example on a Developer Edition org, shown as follows):
The previous screenshot shows that the current org has at least two kinds of community licenses, the Customer Community Login and Customer Community Plus licenses. If you don't have a community user license, you won't be able to create any community at all.
