Like a typical newbie I created two wordpress sites, Cornell's Restaurant and Vatrano Park using the Twenty Ten theme, modifying the style.css, footer.php and sidebar.php of the theme. I know now, hindsight is 20/20, that if I update wordpress to 3.05 it will overwrite my modified files. I have read the WordPress tutorialbut am unclear on a few things.
I need to create the Child theme directory, add the information header to the style.css, but do I then copy my current style.css, adding the information header, footer.php and sidebar.php to the Child theme folder?
Then I activate the theme through the dashboard?
As always thank you all for the help provided in these forums. Hopefully some day I will understand this enough to help idiots like me that don't research before they jump!
