Usage 

This section explains how to set up and use EXT:handlebars_forms in a TYPO3 project.

The extension works in two phases:

1. Form renderer – HandlebarsFormRenderer is registered with EXT:form. When a form is rendered on the frontend, EXT:form delegates rendering to this class, which resolves a Handlebars view based on the TypoScript configuration under plugin.tx_form.handlebarsForms.
2. Data processor – The Handlebars template is expected to call the process-form data processor. This processor walks the EXT:form renderable tree and builds a plain PHP array from it using HBS_* content objects. The resulting array is passed to the Handlebars template as its context.
