How can I add custom ancillaries into the game?

[Fatecheater]

After looking through some files, mainly the export_descr_ancillaries, I figure that the process of adding custom ancillaries into the game includes 3 segments:

1. an image file to ui/ancillaries folder, .tga format, 33x41 pixels.
2. modification to text/export_ancillaries.txt file to include the description of the new ancillaries.
3 modification to data/export_descr_ancillaries.txt to determine the new ancillaries's effects.

Is that all I need to do? Please correct me if I am mistaken somewhere, 'cuz I am just starting to learn to do some basic stuff.

The idea is: I want to add some weapon ancillaries into the game, something like famous swords in history such as Chatlemagne's Joyeuse, Roland's Durendal, England's Sword of Mercy,... (something that really EXISTS, not mythical swords like Excalibur or Balmung). Therefore, I think it will be reasonable if those ancillaries are made UNIQUE just like all Holy relics ancillaries.
