To help you keep track of your content, Buffl offers you several ways to organize your content. You can learn how this works in this article.
Your content is organized into courses and card sets. You can think of a course as a folder that contains card sets.
A card set contains the actual learning content such as flashcards, multiple choice cards, or story cards.
You can also share courses with other users and edit them together. You can learn more about this in the article "Share course".
The archive contains courses that you do not want to delete, but want to hide from your library. Archived courses can currently only be restored via the web app.
