Add Mod to Categories

I was wondering how to add my mod to the categories section. So I can update the categories through the category manager in the admin section.

Thanks for your help.

Not sure that understood you! What do you mean (make new module, or add your existing code in modules section)?

I made a new module and it installs and operates properly.  I want to add categories to it, business types.  so I can use the main page block to show them

• examples:

1. 1. architects
   2. child care
   3. restaurants

I would like to use the dolphin categories section.  so I could use the dolphin admin categories section to update it.

Thanks SashaE for your time and your quick response
