First, you could try following our  General Installation Guide or Price Per Option – General Installation guide which both show how to install Product Personalizer snippets into almost any theme.

If you don’t feel comfortable doing this, or you’re not happy with
the way the installation looks, we’re more than happy to help out :).
You can submit an installation request, and our team will gladly take a look to make any adjustments as needed. Installation is always free of charge – we know you want to get up and running with Product Personalizer as soon as possible, and we’re here to help.
