What’s in this document  
We get you started creating a Fitbit® account and making sure your scale can 
transfer the data it collects to your dashboard. The dashboard is where you may set 
weight goals, analyze historical data, identify trends, log food and water, keep up 
with friends, and much more. As soon as you’re done setting up your scale, you’re 
ready to begin your weigh-ins. To find more information, tips, and troubleshooting, 
please browse our comprehensive articles at help.fitbit.com.
