# 1. Simply visit https://notica.us
# 2. You'll be provided a new variation of the website which will look
#    something like: https://notica.us/?abc123.
#                                         ^

#
#    Your token is actually abc123 (do not include/grab the question mark)
#    You can use that URL as is directly in Apprise, or you can follow
#    the next step which shows you how to assemble the Apprise URL:
#
# 3. With respect to the above, your apprise URL would be:
