This is controlled with the metadata key [`visibility`](00001006020000#visibility). The following values are supported: When you install a Zettelstore, only some zettel have visibility “public”. One is the zettel that contains [CSS](00000000020001) for displaying the [web user interface](00001014000000). This is to ensure that the web interface looks nice even for not authenticated users. Another is the zettel containing the Zettelstore [license](00000000000004). The [default image](00000000040001), used if an image reference is invalid, is also publicly visible. Please note: if [authentication is not enabled](00001010040100), every user has the same rights as the owner of a Zettelstore. This is also true, if the Zettelstore runs additionally in [read-only mode](00001004010000#read-only-mode). In this case, the [runtime configuration zettel](00001004020000) is shown (its visibility is “owner”). The [startup configuration](00001004010000) is not shown, because the associated computed zettel with identifier `00000000000096` is stored with the visibility “expert”. If you want to show such a zettel, you must set `expert-mode` to true. # Examples By using a [query expression](00001007700000), you can easily create a zettel list based on the `visibility` metadata key:
