Step 1: Set the various options at Classieds->Options
Step 2: Setup the categories and/or subcategories.
Step 3: Setup (if you need them) Custom fields. Please note that fields are reusable, so
in case that for example you want to use twice the field "Age" you don't need to
create it 2 times. One is enought.
Step 4: Setup Custom fields groups. You can add as many fields as you want to a group, and
then to assign this group to one or more, or all categories. Please pay attention
for unique display order of the groups.
