21 | ## Deploy
22 | 
23 | Want this for your repository? Simply upload the [`index.php`](/index.php) to any web server with PHP installed.
24 | 
25 | > **Note**
26 | > You may need to manually create the `views.txt` file adjacent to the `index.php` and enable write permissions for it depending on your server configuration.
27 | 
28 | > **Warning**
29 | > Heroku is not recommended for hosting this project since it has an ephemeral file system and will remove the `views.txt` when the source code is refreshed.
