Once this feature has been turned on for your account you can go to your organization view, click the gear icon and then "Basic Settings".
Next you will click on "Customize Header Logo" and you will have the ability to upload a logo image, customize the link (for ex. to your website/intranet etc.) and select a dark or light background.
Once you have added this feature you will no longer see the "Brandfolder" logo in the upper left, you will now see the Custom header logo that you have uploaded.
