A preset is a named bundle of settings the mod can load from a file: a nation, a government, an economy, a military doctrine, a war, a server ruleset, or a library of sub-nations. Warring Nations ships many of them, and every one of them is a file you can copy, change, and install.
Build one below and export it. Nothing here is uploaded anywhere; the page runs entirely in your browser and hands you a file at the end.
/preset schema on the server to export one.
config/warringnations/presets/import/ on the server. Files there are never loaded automatically, so nothing changes until you say so./preset import in game to see what is waiting, then /preset import <kind> <file> to check yours.confirm./preset reload to make it live, then /preset info <id> to confirm the server sees what you expect.Nothing here is required. A preset is a plain JSON file, and every kind has its own directory under config/warringnations/. Drop a file straight in, run /preset reload, and it loads.
A file whose id matches one the mod ships replaces it, which is how you customise a bundled preset without editing the jar.
This page exists because a form that knows every legal value beats remembering them. It is not a different system, and it produces the same file you would have written by hand.
