First, click on "Add Another team" and click on the "Select One" drop-down box. Select the league website your league belongs to. To add you account for that league, please input your username or password (or copy and paste your league URL whichever is asked of you).
If you reach a screen that asks you to authenticate access to your account, then please allow it, as this will allow us to sync with your league. Once FantasyPros has synced with your account, then you will see your leagues from that website on the screen once you've completed the previous steps. Please select the league you want to import by clicking on the blue "Import" button.
Then, press the "Go to My Playbook" button to push that data over into My Playbook and start using the tool immediately with your imported league.
