First you’ll need to log into the site. Once you can see the dark bar across the top, hover over your name near the top right. A menu will drop down, with a link to ‘Edit My Profile’. Clicking this will bring you to your profile update tool.
Use the scroll bar to move between the different options and information areas that you can fill in to populate your profile, including ways to contact you, information about yourself & your business, and a photo or logo. Once you’re done, you can click the blue ‘Update Profile‘ button to save your changes.
