+            In a WeaponSlot there can be only one "Weapon", but a Weapon can have several @ref orxonox::WeaponMode "WeaponModes".
+            A WeaponMode is what one intuitively imagines as weapon. (E.g. RocketFire, LightningGun, LaserFire are weaponmodes)
+
+            A WeaponSlot is created in XML (in a weaponsettings file), which can be done in the following fashion:
