We will start off by creating a simple shader graph:

- Then, drag and drop the material onto our sphere object in the scene, so we can see our shader being used in action.
- Now that the setup is done, we can start creating the graph. If you select the shader, you should see that, from the Inspector tab, there will be a button that says Open Shader Graph. Click ...
