     ## Modularised content
-    The standard content available through our syndication service is based on the full pages on the NHS website. With our modularised content, you can instead choose to use shorter, more specific sections of content (called “modules”) from our pages. This means you can show your users only the content that’s most relevant to them. You can also use this content more easily in services like apps and voice assistants.
