 This page introduces the basic concepts that relate to working with the Input System. They relate to the steps in the sequence of events that occur when a user sends input to your game or app. The Input System provides features which implement these steps, or you can choose to implement some of them yourself.

It starts with the User icon, which then leads into the Input Device and its Controls icon. This then leads into the Action Map and Actions concept. The Input Device and Action Map and Actions icons are collectively grouped under the Binding header. This leads into the final icon representing your action code.](Images/ConceptsOverview.png)

 The Action Asset appears in your Project view, and is named "InputSystem_Actions". This is where your new configuration of actions is saved, including any changes you make to it.

 ## The default actions
 
 When you create and assign default project-wide actions using the method described above, the Action Asset comes pre-configured with some default Actions such as "Move", "Jump", and more, which suit many common app and game scenarios. They are configured to read input from the most common types of input controller such as Keyboard, Mouse, Gamepad, Touchscreen and XR.
