# API

The forms API is packaged as a function that you call to render a form on top of a DOM element. The function takes in the target DOM element and a configuration block, works out the schema, options and layout information that is needed, and then renders the form.

**Start here:** [Usage](/documentation/gitana/4.0/forms/api/usage.md), then [Views](/documentation/gitana/4.0/forms/api/views.md), then [Layouts](/documentation/gitana/4.0/forms/api/layouts.md).
