Help!idiots Guide Please!

Hello.I want to learn how to mod.Look now there was a thread saying how to give the julii hoplites and stuff like that.But I dont want to just know how to add more units but to CREATE my own units from scratch.How exactly is this performed?Do I have to buy any softwar or anything?Im completly new to modding but I would like to learn.Thankyou

What I mean to say is that are there any places to get a free downloadable modding kit for rome total war?thankyou

You need Caligula and Hadrian to make units.
