 You may need to allow the execution of the static PHP CLI shipped with the Workflow. To do so, right click on the workflow in Aflred and choose "Open in Finder", then, if you are on a M1 or greater, right on the `bin/php-8.2.13-cli-macos-arm64` (otherwise use the one ending with `x86_64`) file and choose `Open with → Terminal`. You should be prompted by macOS to indicate if you trust this executable or not, choose as you prefer (if you refuse, the workflow will not work), then quit the Terminal app.
 
+## Usage
