### ServerLess
> You need to configure an environment variable name `WEBSTACK_SCREENSHOT_SERVERLESS`, and the value of the environment variable can be any value you want, e.g. `true`.
> You may need to manually configure font files if the intercepted site contains text in other languages.
>
> Configure the environment variable name `WEBSTACK_SCREENSHOT_FONTS`, the environment variable value can be a url or a path, multiple font files need to be split by `,`. url address must be `https://`, path must be an absolute path.
