Which folder contains the html file to customize the about page? Right now it shows username, number of likes and the hello world introduction.
You can edit the about page in the admin dashboard (ie: https://example.org/i/admin/settings/pages) or edit the blade view in
resources/views/site/about.blade.php, keep in mind if you do edit the blade view you should run
php artisan cache:clear as it gets cached.
Lots of good info!
