 You can create, delete and manage users of your instance. You can change the scan path, password, name and e-mail of a given user.
 
+**Please note:**
+In LibrePhotos, the file system acts as the definitive source of photo organization. This means that folder structure dictates how photos are grouped and accessed within the application.
+
+To isolate users and their photo collections, create separate subfolders for each user on your host system (e.g., /data/user1, /data/user2, etc.). Then assign each user their respective subfolder as their scan directory in LibrePhotos. This ensures that users only see and interact with the photos in their designated directories.
+
+If multiple users are assigned the same scan directory (e.g., /data), all photos within that directory will be accessible to all users. LibrePhotos treats the directory as a global source of photos, meaning that every user linked to the directory will see all its contents.
+
+While the application saves metadata (e.g., tags, albums, facial recognition data) on a per-user basis in its database, it doesn’t inherently restrict access to the photos themselves. Access permissions must be managed through the file system / paths.
+
+The separation will also not keep the photos "private" as the admin of the host system can see all the images.
