Scrum for Trello by Sean Colombo

Scrum for Trello adds functionality to the awesome trello.com for use in Scrum projects.

Add estimates or record time-spent directly on Trello cards. Shows sums at the top of each list and the top right corner of each board.

To use, simply open a Trello card click the title of the card to edit it. There are buttons with Fibonacci numbers (1, 2, 3, 5, 8, ...etc.) to let you quickly add an estimate. You can also type in the estimate or the time-spent. To type an estimate, just surround it in parentheses like this: (4) to type the amount of time-spent, put that in square brackets like this: [2]. Those numbers can appear anywhere in the title, but a common convention is to put the estimate at the beginning of the card and the time-spent at the end, like this: "(8) Create Firefox Extension [4.5]". Decimal numbers are accepted for both values.
