How can I delegate tez to a baker?

If you're looking to delegate the entire tz1 manager account balance to a single baker, use the "Delegate" tab in the main view on the right. Once the operation completes the address of the baker should appear below the manager address. If it does not, click on the refresh button at the top right.

If you'd like to delegate to more than one baker, use the “Add a Delegate” button on the side bar and fill out the necessary information. Please remember to keep at least 3xtz in your manager account.
