(1) You will need to have WordPress and a core theme installed before starting. I highly recommend using the HELLO Elementor theme from Elementor, which you can download from the wordpress.org repository. It is free, light weight, super easy to use & works well with my template.
(2) Make sure you have previously installed the Elementor PRO & Happy Addons plugin before starting. This template kit does need the PRO version in order to use the popup & signup forms. If you plan to add another form plugin, like Ninja Forms, then the free Elementor will work with the rest of the template

The above does include an affiliate link. I do get a benefit if you choose to purchase through the link. I only recommend products I use myself and/or trust implicitly.
