Thank you for the answer, unfortunately I don't have the knowledge to understand it. Currently, I only know that when I start the terminal (bash), I can enter a command, e.g.
docker exec -ti flarum extension require sycho/flarum-private-facade:"*"
- to install the extension.
If it wasn't a big problem, I would ask you to indicate the steps to be taken for a complete layman.
Thank you.
