The current design requires to add all projects manually in the dependency block of the root project:

dependencies {
  dokkatoo(projects.foo)
}

Adding some default mechanism would be nice to not add all projects manually. This is somehow annoying with projects containing many projects.

One option:
Use a build service to register a project when the dokkatoo plugin is applied.
The root project should create the build service (it is evaluated at first) and could depend on the registered projects using dependencies.addLater.
