+# Virtual buttons
+You can find this sample in the tutorial project: **Menu** → **Virtual buttons** 
+
+## 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.

+# Editor properties
+You can find this sample in the tutorial project: **Menu** → **Editor properties** 
+
+## Explanation
+This C# Beginner tutorial covers how to expose editor properties for Stride Game Studio. By creating a public variable at the top of our script, we can create editor properties. Some of the most common properties are demonstrated. We can also create public variables that are not shown in the editor.

+# Delta Time
+You can find this sample in the tutorial project: **Menu** → **Delta Time** 
+
+## 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.

+# Instantiating Prefabs
+You can find this sample in the tutorial project: **Menu** → **Instantiating prefabs** 
+
+## Explanation
+This C# Beginner tutorial covers how to instantiate prefabs. A prefab is a "master" version of an object that you can reuse wherever you need. When you change the prefab, every instance of the prefab changes too. A prefab that is instantiated by code does not give you a new prefab object, but instead gives you a list of entities. As long as these entities are not added to the scene, they wont be visible and attached scripts will not be executed.

+# C# Beginner
+These tutorials cover the beginner principles of using C# when working with the Stride game engine. Start here if you are new to Stride. Note: these tutorials are not a introduction to C# itself. Although having some coding experience is useful, it is not mandatory to get started with these tutorials. You can create the C# beginner tutorial project by starting the Stride launcher. Create a new project and select the template: Tutorials -> C# beginner. Every single scene is loaded as a child scene and demonstrates a sample script. 
+
+All tutorials have a Youtube video. You can watch the entire Beginners playlist here: https://www.youtube.com/playlist?list=PLRZx2y7uC8mNySUMfOQf-TLNVnnHkLfPi

+# Linear Interpolation
+You can find this sample in the tutorial project: **Menu** → **Linear Iterpolation** 
+
+## Explanation
+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. Stride exposes several Lerp functions for various types. Among them are Vector2, Vector3 and Vector4.

+
+
+## Code
+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.

+This C# beginner tutorial covers how to get and remove components. Components are one of the most important concepts in Stride. Every entity in the scene has a list of components.

We can attach these components to entities by using the editor or we can attach them by code.
