On Supernotes you can share just a single card with someone, or an entire hierarchy of notes (if you share a parent card). 'En masse' knowledge sharing is easy, and secure with simple but powerful permissions. To get started with sharing a look at the video walkthrough below - we're been developing so quickly that it's a little out of date but the main concepts have remained the same and are helpful to understand.

A share button can be found on every card, the third icon along the bottom row. If you have shared or joined a card, a number next to the icon indicates how many people have access to it.

Clicking this "share" button will open up the sharing menu, which has two distinct options. Either share a card using a link or if you have a friend on Supernotes you can invite them directly to a card.

You can generate multiple share links to share with other users so that they can "join" your card. Share links can also be used to create public share pages and embed cards with permissions that you choose.

If you are interested in learning more about how share links work, please read here.

At the bottom of the share menu is a member list of all the regular users who have access to the card. You can change user roles, promoting trusted users to Moderators and demoting others to Readers. Authors and Moderators are able to remove members permanently. For more information about roles find them here.

You can also invite your friends to cards using the member list. Just type their 'username' and a prompt will appear asking you to add them!

Received a link / four word code to join a card? Easy. Click (or tap if you're on mobile) the  + , 'Command Prompt' button and click 'Join'. A dialog will appear where you can enter the valid share code / paste the share link. Upon which a preview of the card will appear. You can then choose whether you would still like to join it or not. The real power behind Supernotes is when you start joining cards inside of parent cards, find out more about hierarchical organisation here. 

If friends have added you to a card directly, these cards will appear in your 'Invitations' (the little envelope icon in the bottom left). Here you can decide to 'accept' or 'decline' a card before it is added to your library, along with information on who shared it with you.

When you join a parent card that has a deeply-nested hierarchy, you will only see the immediate children. You can discover the nested children by opening up those child cards which also have children by double-clicking their titles.

The reason we do this is when sharing lots and lots of cards, the person who is receiving the shared cards does not get overwhelmed with too many cards in their library without first realising where they are.

For example, if someone shares a “Books” card with two child cards, with a structure like so:

When I join the “Books” card, I will only see the two child cards called “Of Mice and Men” and “Lord of the Flies”. If I open the “Of Mice and Men” card I will see the 40 child cards and receive automatically new cards added in that space. I might not want to read “Lord of the Flies” so if I don’t open it, I won’t see the 100 child cards, and they won’t clutter up my library; even though I technically have access.

You can edit cards in real-time with friends and see their cursors appear while you are typing on different devices – great if you are planning a trip together, brainstorming a new marketing idea or writing up lecture notes.
