 ## Explanation
 This C# Beginner tutorial covers how to add and remove components. In the previous tutorial we learned how we can retrieve components that are already attached to an entity through the editor. This tutorial shows that we can accomplish the same thing by code. We can add the same component several times to the same entity. We also learn how to remove all of components of the same type again.

 ## Explanation
 This C# Beginner tutorial covers the retrieval and usage of delta time. A games tries to update itself as often as possible. The amount of times it updates in a single second is called 'Frames Per Second' or shortened to 'FPS'. If we wanted to update a timer value, we would need a value that takes into account what the current amount of frames per second is. That is what delta time is used for. So whether your game runs 30 FPS or 120 FPS: you always want to have the same time scale.

 ## Explanation
 This C# beginner tutorial covers how to get and remove components. Components are the of the most important concepts in Xenko. Every entity in the scene has a list of components. The transform for instance is also a component. When we make custom scripts that inherit from SyncScript or AsyncScript, they turn into Components that we can attach to entities. We can attach these components to entities by using the editor or we can attach them by code.

+This C# Beginner tutorial covers linear interpolation which is often shortened to 'Lerp'. Sometimes you want to gradually change a value from a start value to a target value. This process is called linear interpolation. Xenko exposes several Lerp functions for various types. Among them are Vector2, Vector3 and Vector4.

+The example consists of a simple timer that resets after a couple seconds. When the timer starts, a start position and a randomly generated target position are stored. A box will move between these two positions. Every frame a 'Lerp value' is calculated. The lerp value is used to determined what the current position of a moving box should be. Once the timer is done, the current position will become the start position and a new target position is again randomly generated.

+# Loading content
+You can find this sample in the tutorial project: **Menu** → **Loading content from code** 
+
+## Explanation
+This C# Beginner tutorial covers how to load content from code. Assets like models, textures, sound etc can be loaded from during runtime. At that point we no longer speak of assets but of 'content'. This tutorial specifically loads content of the 'Model' type. Loaded content that is no longer required in your scene, should be unloaded again so save up memory. For more information on assets see [Manage assets](../../manual/game-studio/manage-assets.md) 
+
+![Loading content](media/loading-content.png)
+
+## Code
+With the L and U key you can either Load or Unload the model of a mannequin. If there is a model loaded, you can use the S key to spawn a new entity with the loaded mannequin model. The C clears all of the spawned entities in the scene. This demo demonstrates that when models are unloaded, any entities that reference the model are still existing in the scene.

 ## Explanation
 This C# Beginner tutorial covers how to create virtual buttons. Lets say that you want a player to jump when a key is pressed. The space bar is a common option, but what if a gamer wants to have a different key bind to this 'Jump' action? The answer here is the 'Virtual button'. Virtual buttons allow the mapping of one or more keyboard keys, mouse buttons or joystick buttons to a single 'Virtual button'. We can check for the name of that virtual button to see if any of the virtual buttons are triggered.
