I am sure i am not searching with the right keywords. What i want is, when the user open my app for the first time, i want to show a small demo video (10-15 secs) of how to do something on our app. Since I want to embed the video within the app, the output should be really small. Also if its desktop, mouse would be visible on the screencast. How to do that for the app to show users where they have to click. For example, if i click a button, how will the user see that i am touching that button.
I am thinking people would downvote, but seriously this is not my forte and i dont even know which keywords i should search for.
