Step 1: Basic Interface
Step 2: Basic Workflow
Lets say you get the "Ask for text" action first in your workflow. This action will Open a little window and ask you to type something. Whatever you type will be passed on to the next action. Lets say your next action is speak text. This will read the text from the previous action (Ask for text) and speak it through your speakers.
If your workflow looks like the one in picture three, when the run button is pressed, a window should open, and if you type something in it and press "ok", your computer will say it. Congradulations, you've made your first workflow!
Step 3: Other media workflows
Step 4: Saving
The other option is saving your workflow as an application. To do this, click save as from the file menu. In the file format tab, select Application. A file saved as an application is like a moveable run button in the finder.
