#  To automate the request and renewal of lets encrypt certificates, please follow these steps:
#
#  1) install "dehydrated" for your platform, either using your packet manager, or from GitHub:
#     wget https://github.com/lukas2511/dehydrated/archive/master.zip
#  2) enter the dehydrated directory: cd dehydrated (pakets may install into /etc/dehydrated)
#  3) mkdir -p hooks/joker
#  4) copy the file "hook.sh" into hooks/joker: cp hook.sh hooks/joker
#  5) copy the file "config.sh" into hooks/joker: cp config.sh hooks/joker
#  6) edit the file hooks/joker/config.sh: enter your Joker.com DynDNS credentials (please also see https://joker.com/sf/letsencrypt) 
#     and your domain(s); you may simply replace the sample data with yours
#  7) edit "domains.txt" in the dehydrated directory, and enter the domains and perhaps your alternate names (hostnames) there, as usual with dehydrated
#  8) do not forget to first issue a "dehydrated --register --accept-terms" to enable Letsencrypt for you
#  9) then run dehydrated: dehydrated -c -t dns-01 -k 'hooks/joker/hook.sh'
#     Certs will be put into certs/; you may put this into your weekly cron...
#
#  If something goes wrong regarding "challenge type" or "hook script", you may try to modify the original dehydrated config file in the dehydrated directory:
#  - set CHALLENGETYPE="dns-01" and "HOOK="${BASEDIR}/hooks/joker/hook.sh"
#
#  If multiple challenges have to be solved for the same hostname, you have to add the following line to the original dehydrated config file in the dehydrated directory:
#  HOOK_CHAIN="yes"
#
# Please note: The script is waiting 30 seconds before testing the "challenge" value, to make sure that the nameservers registered the change
