Thanks @Bryan_Fisher for passing on the information on ricecooker!
One point of clarification to add is that the ricecooker is used to bring content from an original source into Kolibri Studio (to then import into Kolibri), but we don’t currently support a functionality to transfer lessons from a Kolibri installation into Studio for sharing across local installations. This is good feedback though and we’ve noted it for future iterations in our roadmap.
The best suggestion we can offer at the moment is to create this lesson structure as a channel in Studio, where each ‘topic’ contains the content of each lesson and then that channel ID can be shared within local installations. This still means needing to replicate the work once, unfortunately, but will save you from having to replicate it for each individual installation. Let me know if you still have questions around this.
