+## Spawner
+
+- Vinifera implements its own spawner, capable of starting a new singleplayer, skirmish or multiplayer game, as well as loading saved games.
+- To start the game in spawner mode, the `-SPAWN` command line argument must be specified.
+- The spawner's options can be configures in `SPAWN.INI`.

+- Information about the local player is read from the `Settings` section, for all other players - from `OtherX` sections, where `X` ranges from `1` to `7`.
+
+In `SPAWN.INI`:
+```ini
+[PLAYERSECTION]
+IsHuman=no                  ; boolean, is this a human player?
+Name=                       ; string, the player's name.

+Port=-1                     ; integer, the player's port.

+- Additionally, AI players (always come after human players) have these options parsed from sections of the format `MultiX`, where `X` ranges from `1` to `8`.

+
+- Additionally, the spawner reads configuration for each house. Player houses come first, in the order of their color (increasing), then AI houses.
+- Alliances are read from sections of the format `MultiX_Alliances`, where `X` ranges from `1` to `8`.
