# Notifico allows you to relay notifications into IRC channels.
#
# 1. visit https://n.tkte.ch and sign up for an account
# 2. create a project; either manually or sync with github
# 3. from within the project, you can create a message hook
#
# the URL will look something like this:
#       https://n.tkte.ch/h/2144/uJmKaBW9WFk42miB146ci3Kj
#                            ^                ^
#                            |                |
#                         project id       message hook
#
# This plugin also supports taking the URL (as identified above) directly
# as well.
