To add a standard slide to your lesson, first click + Add.
Then click on 'Slide'.
You get the option to create a slide yourself or search for a slide in the library. In this article, we will choose 'Create my own'.
You will now see a slide with a default layout where you can insert a title and text. To change this layout, click 'Layout' and choose the layout you want.
If you don't want to use the default text boxes from the layout options, you can choose +Component --> Text. You can freely move this text box around on your slide.
The same goes for images. If you don't want to use the default boxes for an image, you can choose +Component --> Image. You can freely move this image around on your slide.
