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