Hello. I don't understand your question. Do you have some experience with Unity? This is really easy to use them. Only put a script on your camera, adding in your project the folder MyShaders which contains all shaders. Nothing more ++

Download the Zip file. There is a main folder which is named MyShaders. Inside it, you have two folders - one with shaders and a second with scripts. All these folders must be in your Unity project. Put one of the scripts on your camera. Done ++
PS : Respectfully if you cannot import these scripts, I guess that you are a newbie - and you should start with Unity taking a look at a tutorial.
