The topic of this paper are instructions for using the tool in the form of an interactive web tutorial. The introductory part of the paper explains what multimedia is, what types of multimedia exist and which ones are best used so that users remember as much as possible. It further explains what Unity is and what its user interface looks like, and describes all its auxiliary tools within that interface. After that, the tools used in creating a web application are described, namely programming languages: Vue.js, HTML, CSS and JavaScript. It begins by installing certain packages that are required for a Vue.js application, after which the application code is explained. The first thing that is explained is the routes and how to set them up correctly. After the routes, the views are explained. There are 3 views in the project, one of which is the initial screen when we open the application, one view where the videos would be located, and a view called "Script.vue" which contains all the documentation for creating a 2D platformer game. Each view has code explained and an explanation of what that view is used for and what it looks like.
