HashiCorp's Terraform Registry requires every repo to have a main.tf in its root dir. The Consul code is broken down into multiple sub-modules, so they can't all be in the root dir /. Therefore, Consul's sub-modules are in the /modules subdirectory, the example code is in the /examples subdirectory, and the root dir /also has an example in it, as described in root-example.
