How to import time from Trello that has already been spent

Before you started you have to understand how the import works.

3T can recognize the following types of actions for time tracking:
- moving cards between lists
- checking and unchecking checklist items
- commenting start, stop on cards

if you did not use any of those ways then import may not work for you.

Firstly, please, configure 3T according to one or all ways that you did use before
so 3T would be able to recognize and handle all actions during import process.
