version: 0.4.0 (semver)

• Clone the repository.
• Ensure the script is executable. chmod +x cloudflare-ddns-updater.sh
• Set the envionment variables (detailed below) to your domain/account details OR create a settings.conf in the same directory as the script (example syntax below).
  • If using the settings.conf file, it is recommended to ensure the file has the permissions set to 600. chmod 600 settings.conf
• The script can be run manually, or use cron to run it on a schedule.
  • To schedule with cron, open crontab with crontab -e
  • Paste in */10 * * * * /path/to/cloudflare-ddns-updater.sh This will run the script every 10 minutes.

NOTE: The settings.conf takes precedence over environment variables. This is useful if multiple instances of the script is needed.
