If you've never used Clotho before, you want the starter edition. It will keep all your data on your hard drive. It comes with a lot of data already in it to play with and a tour. You won’t be able to share your data, but it’s really easy to install.

If you want to get started using Clotho, but you don’t have the ability to set up a server, you can use the Cloud version. Here, you’ll create an account and database at a commercial provider, and then Clotho will guide you through how to connect to it.
