The following assumes a Linux host, you will need to modify as needed if you are running Windows or macOS; this script should work on any platform.

Note: The record(s) you want updated must already exist on DigitalOcean.

• Clone or download this repository to a new directory of your choice
• Install required dependencies: composer install --no-dev
• Setup the environment: cp .env.example .env && nano .env
• Test run: php update.php, if you see any errors your .env file is probably incorrectly configured
