how to save my containers guide

hello :)

my docker containers number is increasing and I was thinking which should be the best way to save all the configurations, descriptions and the processes needed to put all the containers up and running.

since now I was using a simple text file, since I had not so much to remember, but the configuration is becoming more and more complex.

I was thinking maybe at a kanban board.

what would you recommend?

(I'm not a programmer, that's also why I'm asking) :)
