+Sharing Decks Privately
+
+If you’d like to share decks with a limited group of people (such as a study group or class) rather than the general public\
+you can do so by sharing them outside of AnkiWeb.\
+To share a deck privately, go to the File menu and choose Export. Select a single deck (not "All Decks"), and turn off "include scheduling information".\
+This will produce an .apkg file which you can share with others.\
+You can share the .apkg file by emailing it to people, placing it on a website or shared folder\
+or using a free file sharing service like Dropbox or Google Drive and sending people a link.\
+Both the computer version and mobile clients make it easy to import from an apkg file simply by clicking or tapping on it.\
+AnkiWeb does not have the ability to import apkg files.\
+However, so the recipients of your deck will need to have the computer version or Anki on their mobile device.\
+When a user **imports** an .apkg file, cards that already exist in their collection will be ignored and any new cards will be added.\
+As long as they use the same note type, modified cards will also be updated.\
+**To prevent data loss, cards that have been deleted in the new apkg file will not be deleted in the user’s collection.**\
+**So if you need to delete cards from users' decks for whatever reason, you will need to contact them about it.**
