About the approach of this plugin

Hi, kudos for this awesome plugin.

Would you mind adding a section about "What does this plugin do" to the README. From the first look I thought it would generate a Dockerfile and necessary files for users. I also think it is more user-friendly that way. I don't know if it's possible to change the current approach.

I wouldn't see the point of generating a Dockerfile unless there is a good amount of variation in output (which is unlikely?).

The example in the README however doesn't really convey what the value of this plugin is vs equivalent of whatever it'd be to manually manage in the Dockerfile.
