To check if curl is installed on your computer, open a terminal/command prompt (Windows users: open Powershell), and at the prompt type:

curl --help

If you see a long result showing command usage information, it means curl is installed and ready to use. However, if you see command not found, you can download the curl executable for your operating system here: https://curl.se/download.html
