The Start Page (the public-facing process overview or landing page) is where constituents go to begin using the workflows you've created.
Here's an overview of what's on the Start page:
To get to the Start page for a workflow from an admin account:
Click "Workflows" in the upper nav
Click the workflow you'd like to visit the Start page for
Click the green "Use workflow" button in the upper right.
The URL for your Start page is revealed. Copy the URL and paste it into your browser to visit the page.
Once you're there, you can change the background image for the page and set a short description.
This is also the same link you'll use to include this workflow on your website.
