Settings can be accessed by clicking the gear icon at the top of the Workflow designer. Here you will enter the Workflow Name and optionally a Description. You can also view the Site, List and the way in which the workflow is triggered (these will all be initially set upon the creation of the wokflow).
When to start the Workflow section will show the way in which the Workflow is triggered, and whether it is processed for items created, modified, or deleted by automated processes, along with the option to delay the execution of the Workflow by up to 30 seconds.
Workflow execution history settings will allow you to enable the execution history, producing a worklog and errorlog that can be very useful for debugging and verifying that workflows are running properly.
