When you connect your Trello account to your Zenkit account, you can directly import your Trello boards to Zenkit when you create a new collection.
To connect your Trello account, navigate to your profile settings. Click on the small profile icon in the top right hand corner, click on your name, then go to "Integrations".
Click the toggle next to "Trello" to the "On" position. A popup will appear asking you to log in to let Zenkit use your account.
If you are already logged in to Trello in the browser, you will be asked to allow Zenkit to use your account.
Now when you create a collection by importing a board from Trello, you won't have to log in again for another 30 days.
