What is the best way to use WPMUDEV plugins on my client websites?

Hi, I’m new to building sites for other peopl and I read that I could do this with WPMUDEV, however I wanted to ask and find out what the best practice for this was. Do I still get the WPMUDEV update plugin first and put in my key? I dont want other people to see and possibly use my license though. Or do I just install the plugin? Thanks for the help!!
