# Introduction Firmhouse makes use of Liquid, an open-source template language which provides a safe way to generate user content. This way, you can configure/edit appearance of your Checkout, Self Service Center and add dynamic content to emails and webhooks. Why should I use Liquid? * You want to allow your users to edit the appearance of your application, but don't want them to run insecure code on your server. * You want to render templates directly from the database. * You need a template engine which does HTML just as well as emails. ### Support Need help? Don't hesitate to email with your questions. Or get in touch via the Chat bubble when logged into the Firmhouse portal.
