What's next?
- Make sure you restart Ferdium in order for the recipe to show up
- Customise "webview.js", "package.json" and "icon.svg" (see https://github.com/ferdium/ferdium-recipes/blob/main/docs/integration.md#recipe-structure)
- Publish your recipe (see https://github.com/ferdium/ferdium-recipes/blob/main/docs/integration.md#publishing)`);
