I want to create a website that contains tutorials using a software. Such as Microsoft Office, Photoshop, CorelDraw, and others. I wanted to deliver it from beginning to end, in other words, from beginner to advanced. The material presented in text and video. I will provide the free and paid versions. What do I need? About plugins and themes. Do I need a theme from a third party? And please give advice to me regarding an initial technical step.
