"about the author" is currently under development as part of the user profile. We expect the functionality to be released in 10 days in the next Integra Core package update version 1.2.0
Once available you will be able to implement it in your site too. It will not be automatically applied as it is part of the platform customization and implementation.
More about the user profiles you can read here
If you have any questions how to implement the author about section, please contact our community once the profile component is out.
