Simple modding without tools

[sunsmountain]

It pains me to try and find answers to these simple questions, and i have searched high and low. Here they are:

- How do you add a building to a faction, that can already be built by other factions (for example, paved roads for barbarians)?

- Similarly, how do you add a unit?

The main problem you run into is that you get placeholders instead of the correct building cards on the campaign map. Similarly for units.
I've found the \export_descr_buildings.txt, and the \text\export_buildings.txt, and i read somewhere that unit/building cards can be found in the \ui directory, but where is that??


It's just 1 or 2 units/buildings i want to change myself, i do not want to use tools for this (i want to understand).
