Workflow Studio includes two tutorials that can be accessed from the Help menu. When you first launch Workflow Studio, you are in the management console:

The first tutorial can be accessed by clicking on the “Help…Getting Started” menu option. This will launch the Getting Started guide which is a tutorial that will walk you through the process of downloading a sample Workflow called ExportServices from CDN (using the built-in Community tab) and then running that workflow from the management interface.
Note: The tutorial is in PDF format. On many systems nothing will happen when you click on the “Help…Getting Started” link if you don’t already have a PDF viewer already installed. Sorry about that – we will fix that in the next release.

The second tutorial is available from the Designer interface. The Designer interface is what is used to create or edit a workflow and looks very similar to the Tech Preview user interface:

This tutorial will take you through the process of creating the sample workflow that you saw in the first tutorial. This will demonstrate many of the techniques you will use to build workflows.

If you have any questions on either of these tutorials – post them here. In a future post I will explain some more details behind the Designer interface. Look for more tutorials and samples soon as well.
