This URL Shortener has fully support with ShareX. To use it, just import the configuration to your ShareX. For that you need to open the `Destination settings` => `Other / Custom uploaders` => `Import` => `From Clipboard`.
After you've done this, you need to set it as your standard URL Shortener. For that go back into your main menu => `Destinations` => `URL Shortener` => `Custom URL Shortener`.
