These workflows assume the module is installed and assigned to a menu item you can load in the browser.
Create a category for milestones, publish one article per milestone with created dates matching the story order, set Layout to default or style1, order by Created Date ascending, and assign the module to your About page.
Choose Layout style9 (Horizontal), set Article Field to Order By to Created Date and Ordering Direction to Ascending, and keep Count modest so the horizontal strip stays readable on mobile.
Leave categories broad or empty, set Tags to a dedicated timeline tag, and publish tagged articles. Combine with Featured Articles Only if you want a curated subset.
Enable Item Image and at least one image source (intro, fulltext, or inline). Set Resize Mode and dimensions to match your template. Set Placeholder Path when some articles lack images.
