How do you create a Plasitc SCM Repo from an existing project?

I have an existing unity project for which I want to make a Plastic SCM repo. The only options I see in the windows plastic scm project are "Create New Repository" and "Create Workspace From a Repository". How do I create a Repository from an existing set of local files?

1. You will need to create a new repository (database stored on the server-side to store the repo history).
2. Then you create a local workspace in your project local path pointing to the repo you just created.
3. Finally, you can checkin your initial version of the project to the repository.
