Click Create new workflow and the window for defining it appears:

Depending on the workflow type, a workflow has different parameters. For example, in case of a workflow processing an SQL query, database connection settings and the SQL query to execute must be set via the workflow parameters.

During the startup phase of a workflow, the workflow might check a pre-condition and stop running if the pre-condition is not met. A common example for such a pre-condition is whether a monitored file system path contains a new file.
