Attachments
Put files and images on a card from the paperclip, a paste or a drag. Needs a sync server.
Attachments are currently supported only with the self-hosting setup: they require a sync server.
Having attachments with the local setup is on the roadmap.
How to attach files to a card?
1. Attachments button on the card
The paperclip in the card header opens the attachments panel.

Attached images can then be referenced via the slash menu:

2. CMD+V with the attachment in the buffer
Focus the card's body, and paste an image.
3. Drag and drop the file to the card
Deleting files
In edit mode on the card, click the x near the attachment to remove it.
