# - as node.js module/client:
#   run command: docker run --rm -it typpo/textbelt node
#     then copy/paste or type in the code to send message as shown README example
#   or run command: docker run --rm -it typpo/textbelt node pathTo/yourScript.js
#     assuming your script has the code that calls the textbelt module to send message
#   or run command: docker run --rm -it -p 8080:9090 typpo/textbelt bash
#     to be taken to the shell for you to debug and test things out
#     e.g. start/stop/query redis, nginx, test/use mutt
#     run textbelt as module in node shell, node script, or start textbelt server

# NOTE: if you use an external redis server and/or external reverse proxy / load balancer
# you will need to handle the network config and mapping such that the textbelt
# docker container can talk to those servers (which may or may not be in their own docker containers)
