Hello @meckelnburg! Thank you for your question. You can combine guides by using prerequisite guides. Our prerequisite guide feature allows authors to create modular guides by adding prerequisites at the beginning of a “container guide” or by placing multiple prerequisite guides into an otherwise empty “container guide.”

Important Note: Guides must have a published release before they can be used as a prerequisite guide.

If you would like to know how to add a prerequisite(s) to an existing guide, use this guide on How to Add Prerequisite Guides.
