1. Log into your Living DNA account; https://my.livingdna.com/signin
2. Select the profile you wish to write a bio for by clicking on "Profiles"
3. Select the profile you wish to edit by clicking on the name in the menu on the left.
4. Scroll down the page to the family matching section, and click "Edit."
5. You can edit any of your Family Matching settings from here. Please enter your details in the text box and select save.
Please be aware that anything written in this section will be visible to all your matches.
