+/**
+ * Usage: node choco-auto.js <projectVersion>
+ *
+ * This script is meant to be ran in the workflow to automatically update the Chocolatey package for Headlamp.
+ * We can run this script manually by following the steps below:
+ *
+ * 1. Ensure that Node.js and npm are installed on your system.
+ * 2. Run this script using the command `node choco-auto.js <projectVersion>`.
+ *
+ * Parameters:
+ * - projectVersion: The version of the project you want to fetch information for (e.g., 0.19.1).
+ *
+ * Ensure that you replace `<projectVersion>` with the actual project version, do not include the 'v'.
+ *
+ * Note: The `choco-bump.sh` script should be located in the same directory as this script and should add changes to the headlamp.nuspec and chocolateyinstall.ps1 files.
