The first step is to open Trello, and Click on the first card you want to connect to another one.. NOTE: Clicking "Add Trello attachment" under the card's Trello attachments area will produce the same results as what will be shown here.  Click Attachment.. You can either choose one of the Recently Viewed Trello cards, or Click in the Search or paste a link field.. Type to Search or paste a link for the card you want to attach.. Scroll down, and Click on the title of the card you want to attach.. The attached card appears on this card.  Click Connect cards.. Click Relate both cards.. That card is now attached to this card.  Click on the attached card.. If you decide you do not want these cards linked any more, scroll down, and Click Remove.   A confirmation message will appear.. Click Remove in the confirmation message.. The connection or removal action is noted in the cards' Activity timelines.  That's it. You're done.
