# To use this plugin, you must have a ZulipChat bot defined; See here:
# https://zulipchat.com/help/add-a-bot-or-integration
#
# At the time of writing this plugin the instructions were:
# 1. From your desktop, click on the gear icon in the upper right corner.
# 2. Select Settings.
# 3. On the left, click Your bots.
# 4. Click Add a new bot.
# 5. Fill out the fields, and click Create bot.
# If you know your organization {ID} (as it's part of the zulipchat.com url
# after you signup, then you can also access your bot information by visting:
# https://ID.zulipchat.com/#settings/your-bots
# For example, I create an organization called apprise. Thus my URL would be
# https://apprise.zulipchat.com/#settings/your-bots
# When you're done and have a bot, it's important to remember the username
# you provided the bot and the API key generated.
#
# If your {user} was : goober-bot@apprise.zulipchat.com
# and your {apikey} was: lqn6mpwpam6VZzbCW0o7olmk3hwbQSK
#
# Then the following URLs would be accepted by Apprise:
# - zulip://goober-bot@apprise.zulipchat.com/lqn6mpwpam6VZzbCW0o7olmk3hwbQSK
# - zulip://goober-bot@apprise/lqn6mpwpam6VZzbCW0o7olmk3hwbQSK
# - zulip://goober@apprise/lqn6mpwpam6VZzbCW0o7olmk3hwbQSK
# - zulip://goober@apprise.zulipchat.com/lqn6mpwpam6VZzbCW0o7olmk3hwbQSK
