+# Mission Script API — Documentation
+
+This folder documents the API available to mission scripts. Mission scripts derive from `AMission` and are loaded by the game at runtime.
+
+Mission scripts also use additional types such as `LimbNames`, `NamedDamageTypes`, `Point2d`, and `Point3d`; those are summarized in [External Types](External Types.-).
+
+## How mission scripts are loaded
+
+1. The game loads a **battle** (one `ABattle` instance) via `IScriptRemote.loadBattleScript`.
+2. Missions are attached with `loadMissionScript(fileName, missionNumber, scriptFileName)`, which instantiates a class named `Mission` that inherits from `AMission`.
+3. Each mission's `Init(battle, missionNumber)` is called; then the battle runs and invokes the mission's virtual `On*` methods in response to game events.

+## Quick start
+
+1. Create a class `Mission` that inherits from `AMission`.
+2. Override `OnBattleInit`, `OnBattleStarted`, and any `On*` events you need (e.g. `OnTrigger`, `OnActorCreated`, `OnAircraftKilled`).
+3. Use `GamePlay` (IGamePlay) for querying actors, triggers, spawning groups, HUD messages, and section files.
+4. Use `Time` (ITime) for game time and tick conversion (e.g. with `Timeout`).
