hi
I've always seen it, but never use it, but now I was going to take advantage of this, but I don't get it:
I only see a local folder in the admin/includes

Should I create a new one on the includes also ?

I just need to copy the configure files and change the paths ? or this is all happening in the admin/includes/local ?

I've google it a little, but the word local sends me to different contexts

Thanks
