Hello ChoSze. To develop the guideline for the use of something is to describe how it may be handled or used. examples: Develop the guideline for the use of the security system "X". - Double click on the app "X" icon - enter your login and password - set the camera you want to open in your screen our to "multicamera view" - etc.. etc.. etc... Develop the guideline for the use of a microwave - plug the power cable into a socket - press "on/off" button - Set the potency by pressing the "potency" button till you see the percent you think adequate - Set the time of heating pressing the numbers on the "numbers panel" - Press "start" button. hope I did help.
