Dockerfile

# Note: This file contains four environment variables near the end. Change
# (#1)  these to match your settings or you will not be able to connect the bot
#       to a Matrix homeserver.

# Note: This Dockerfile uses multi-stage builds. Therefore, the required Docker
# (#2)  version is 17.05 or (preferably) a later version on the client and
#       server side of Docker.
