How to Install the Signup Form on Wordpress
Step 1: Copy & paste the Prefinery.js code into the Footer.php file of your Wordpress Theme.
Step 2: Copy & paste the Prefinery form code into the Visual Editor of a Wordpress Post or Page.
As Prefinery does not currently have a Wordpress plugin, you will need to edit your theme. From the Wordpress Appearance → Editor menu you will be able to customize your theme. All Wordpress themes should have a Footer.php file which will typically end in something like the following:
Paste the Prefinery.js code just before the call to wp_footer()
The popup or embedded form code can be pasted directly into a Wordpress Post or Page.
