The author introduces two Github Actions that can help automate the exporting of Godot games to HTML and uploading them to itch.io. After creating a game on itch.io and uploading a first build with the Github Action, the upload can be automated on every push. The actions can be customized to fit specific needs, and examples are provided. Other platforms and exports can also benefit from the actions, such as uploading to websites or other HTML game portals, or uploading games in formats other than HTML5 to itch.io. The author welcomes questions or feedback from readers.
