override question

Getting ready to move to a new host (goodby eig) and I am just going to start from scratch with a new zen cart. I dont think I did this right last time and I want to do it right now. I have read the template and override tutorials probably 10 times each and I still dont quite understand if I should name my override files the same as my template.

Lets say I am going to use the template "westminster new" for my stores theme. Would I name my new override files "custom" or should I name it the same name as the template "westminster new" I plan on using?
If I named it custom and then installed the westminster new template will it know what to do ?

You should call the override folders the same as the folder name you use for the template. Then Zen Cart will automatically pick those folders up as overrides

OK all of my override folders I shall name westminster_new
Thank you very much for the help.
