# Base docker image for running Evennia-based games in a container.
#
# Install:
#   install `docker` (http://docker.com)
#
# Usage:
#    cd to a folder where you want your game data to be (or where it already is). 
#
#	docker run -it -p 4000:4000 -p 4001:4001 -p 4005:4005 -v $PWD:/usr/src/game evennia/evennia
#    
#    (If your OS does not support $PWD, replace it with the full path to your current 
#    folder).
#
#    You will end up in a shell where the `evennia` command is available. From here you
#    can install and run the game normally. Use Ctrl-D to exit the evennia docker container.
#
# The evennia/evennia base image is found on DockerHub and can also be used
# as a base for creating your own custom containerized Evennia game. For more
# info, see https://github.com/evennia/evennia/wiki/Running%20Evennia%20in%20Docker .
