Installing Docker

Hello, I’ve managed to install Wappler & Nodejs on my Ubuntu System. I also have Docker installed. When I click on ‘System Check’ in Wappler, I see that everything is installed correctly except for Docker. There is no mention of it at all. I have completed the course by Ken Truesdale but his course is limited to Windows/Mac users only. He also installs Docker Desktop which I don’t have on my linux system.

How do I get this to work? I’m really new to the whole Linux ecosystem so I would appreciate any and all help/advice.

Thanks,
Ken
