How do I go about making a heavily modified parent theme into a child theme?
I've been working with WP 3.0, twentyten theme. Did a bunch of mods to different files (I'm not a techie in the least but have figured out a few things and tweaked here and there). Recently read about the suggestion to work with a child theme in order to not lose mods.
So I backed up/saved all the files from WP 3.0 twentyten theme and upgraded to WP 3.3 which comes with the TwentyEleven theme and would like to use the previously modified parent theme as a child theme to override the updated version. I've read about putting the info in the header for the child theme to reference the parent theme however I'm lost. I've made changes to the CSS stylesheet, and a quite a few other files How do I get everything that was working together in the previous parent theme (which I want to convert into a child theme) to take effect with the upgrade?
Let me pre-empt WP veterans first-I'm rather a dunce with coding and terminology so I'd appreciate any and all help to be explained in the most basic of terms. Step by step direction are most appreciated.
Right now my website is down because of the aforementioned and I'd like to get it up and running with the quickness.
