-        The PickupRepresentation class represents a specific pickup type (identified by its PickupIdentifier). It defines the information displayed in the GUI and how PickupSpawners that spawn the pickup type look like.
-        They are created through XML and are registered with the PickupManager.
+        The PickupRepresentation class represents a specific pickup type (identified by its @ref orxonox::PickupIdentififer "PickupIdentifier"). It defines the information displayed in the GUI (PickupInventory) and how @ref orxonox::PickupSpawner "PickupSpawners" that spawn the pickup type look like.
+        They are created through XML and are registered with the @ref orxonox::PickupManager "PickupManager".
+
+        Creating a PickupRepresentation in XML could look as follows:
+        @code
+        <PickupRepresentation
+            name = "My awesome Pickup"
+            description = "This is the most awesome Pickup ever to exist."
+            spawnerTemplate = "awesomePickupRepresentation"
+            inventoryRepresentation = "AwesomePickup"
+        >
+            <pickup>
+                <SomePickup />
+            </pickup>
+        </PickupRepresentation>
+        @endcode
+        As you might have noticed, there is a parameter called <em>spawnerTemplate</em> and also another parameter called <em>inventoryRepresentation</em>. Let's first explain the second one, <em>inventoryRepresentation</em>.
+        - The <b>inventoryRepresentation</b> specifies the image that is displayed in the PickupInventory for the specific type of @ref orxonox::Pickupable "Pickupable". More technically, it is the name of an image located in the <code>PickupInventory.imageset</code>, which in turn is located in <code>data_extern/gui/imagesets/</code>.
+        - The <b>spawnerTemplate</b> specifies how the type of @ref orxonox::Pickupable "Pickupable" (or more precisely the @ref orxonox::PickupSpawner "PickupSpawner", that spawns that type of @ref orxonox::Pickupable "Pickupable") is displayed ingame. It is a @ref orxnox::Template "Template" defined in XML. The <em>spawnerTemplate</em> can be specified as follows (keep in mind, that the template needs to have been specified before the definition of the PickupRepresentation that uses it).
+        @code
+        <Template name="awesomePickupRepresentation">
+            <PickupRepresentation>
+                <spawner-representation>
+                    <StaticEntity>
+                        <attached>
+                            <!-- Here you can put all the objects which define the look of the spawner. -->
+                        </attached>
+                    </StaticEntity>
+                </spawner-representation>
+            </PickupRepresentation>
+        </Template>
+        @endcode
+
+        For the purpose of them working over the network, they are synchronised.

+            The PickupSpawner class is responsible for spawning @ref orxonox::Pickupable "Pickupables" of a specific type.
+            Furthermore it can be specified how long the time interval between spawning two items is and how many @ref orxonox::Pickupable "Pickupables" are spawned at maximum, amongst other things. The parameters that can be used to further specify the behaviour of the PickupSpawner are:
+            - The <b>triggerDistance</b> can be used to specify how far away an entity has to be to still trigger the PickupSPawner (and thus receive a @ref orxonox::Pickupable "Pickupable" form it). The default is 10.
+            - The <b>respawnTime</b> is the time in seconds that passes until the PickupSpawner is enabled again, after having spawned a @ref orxonox::Pickupable "Pickupable". The default is 0.
+            - The <b>maxSpawnedItems</b> is the number of @ref orxonox::Pickupable "Pickupables" that are spawned by this PickupSpawner at the most. The default is -1, which denotes infinity.
+
+            A PickupSpawner is created in XML, which can be done in the following fashion:
+            @code
+            <PickupSpawner position="-100,0,-100" respawnTime="30" maxSpawnedItems="10">
+                <pickup>
+                    <SomePickup >
+                </pickup>
+            </PickupSpawner>
+            @endcode
+            As we can see, since the PickupSpawner is a StaticEntity, it also has spatial coordinates. We can also see, that the type of @ref orxonox::Pickupable "Pickupable" which is spawned hast to be specified as well.
