Unfortunately, we don't have a tutorial for MDB5 that you are talking about. I sent you the tutorial we have as an example of how to add MDB in Theme.

If you can add files via FTP, you may have the option to add MDB via FTP and edit the files to add the necessary imports (which David shows in the tutorial on YT).

I guess you are editing pages as described here: https://www.greengeeks.com/tutorials/how-to-view-and-edit-wordpress-theme-files/ so you should be able to add the necessary code

Hello Grzegorz, I have already watched the video. In the video, the theme is installed on your own PC with MDB CLI. However, I work with an external web space provider. There I can only move data via an FTP transfer programme. As far as I know, the terminal program is an application that only runs on my computer and with which I cannot work on a server of a hosting provider. I only know how to install themes on the external server under wordpress by uploading zip files. This case is not described in the tutorial. Can you give me more information here? What I am missing is a Tutorial for the manuale installation when you don't work on your own PC.

Thanks a lot

On our Youtube channel you will find a tutorial on how to create a WordPress Theme. In your case, you will need this tutorial fragment: https://www.youtube.com/watch?v=vROnt5uIjzc&t=163s

The tutorial was created using MDB CLI, but it should look similar for you. In the video you will find information on how MDB was added to the project
