+Missions can include `CfgStartingEquipment.hpp` from `description.ext` to set
+new-player loadout and initial virtual arsenal or garage unlocks without
+recompiling the framework.
+
+```cpp
+#include "CfgStartingEquipment.hpp"
+```
+
+`loadout[]` uses the standard Arma loadout array shape. `Unlocks.Locker`
+supports `items[]`, `weapons[]`, `magazines[]`, and `backpacks[]`.
+`Unlocks.Garage` supports `cars[]`, `armor[]`, `helis[]`, `planes[]`,
+`naval[]`, and `other[]`.
+
+The extension defaults are intentionally empty. The server seeds mission
+starting unlocks only when a player does not already have persistent owned
+locker or garage records.

 The current filter is global for the mission. Revisit per-store profile support
 if individual vendors need different inventories.
