There are two ways to create cards in your playbook - Capture from Activity Feed, and Create a Card.
Capture From Activity Feed
To capture a post from the activity feed, select the extras menu and then select ‘Add to Playbook’. Choose the playbook, if you have more than one playbook, select the playbook and click ‘send’ button. The post will appear in your playbook.
Create a New Card
To add a new card in a playbook, select your playbook in ‘Playbook’ tab and select the add button to create a new card directly inside the playbook. Use either text or audio recording as the card content and you can upload image and video as an attachment.
Check the ‘Post this to shared update?’ box to add this card as a shared update in your activity feed.
Delete, Leave or Edit the Playbook
You can leave the playbook at any time if others have shared with you. Go to playbook tab and then select the playbook shared with you. Click "Leave playbook" on the right hand side of the screen.
Owners of the playbook can not leave but they can edit or delete it. Go to playbook tab and then select the playbook under "My Playbooks". Click "Edit playbook" or "Delete Playbook" on the right hand side of the screen. Deleting a playbook will remove access for all users of that playbook.
