Embedding a form on your own website is easy!
Navigate to the form you want to embed, and scroll to the bottom of Settings.
Click </> Embed, too see the short code snippets that you should copy and paste into the place you want the form to be visible on your web.
This code needs to run only once. Try to put it in a master template that is loaded for all pages, preferably between the <head></head>-tags.
This code should be placed where the form should be generated, and are unique for each form.
