Add this to the documentation

[matiasilva]

Hello,

Just want to chime in and say that the work being done here is great and could serve as another method of installation for BBB. May I suggest that you submit a pull request to update the existing documentation to add a fourth installation method. Originally it seems that the docker repo made by BBB was meant for testing but you have managed to turn it into production. This may be very helpful to others who don't yet know about this.
