Importing a Trello board is a simple process. First, export your Trello board as a JSON file.
Next, open the collection you wish to import your board into and click the + button in the top left corner and choose Import instead of Create.
This will open a dialog, choose Trello and browse for your saved JSON file.
Map your Trello users to Favro users and finalize the import.
And that's it! You're ready to carry on your work in Favro.
