# Generic tasks that we always want to happen, regardless
# if the user wants matrix-nginx-proxy or not.
#
# If the user would set up their own nginx proxy server,
# the config files from matrix-nginx-proxy can be reused.
#
# It doesn't hurt to put them in place, even if they turn out
# to be unnecessary.
