HOW TO: Add a Civ/Unit/Building in BTS (Modular XML Modding)

[<Nexus>]

Tags can be overwriten if they aren't empty: 0, -1 or NONE (maybe -1 works as it usually means unlimited, I don't remember)
The text files aren't modular so they have to go to the mod's Text folder. That also means that you cannot simply reuse the text tag reference in a module. Rename it, at least a bit.

The game allows introducing new text files with different names though. As long as they are in XML/Text they will be parsed and their tags will be available. I would assume that you can create an XML file in XML/Text in your module, and as long as it does not conflict with a file name in the base mod it will be included.
