Custom Page Templates are custom designs for WordPress pages. Many of our themes support Custom Pages Templates.
To setup a new page with a Custom Page Template you should:
Creating a custom front page is an easy way to personalise your site with little effort. Read the Custom Front Page documentation for more info on how to do this.
If you want to add your own custom page templates then you should follow the process outlined on the WordPress Custom Page Template documentation. I would recommend using a child theme to make these chages. If you don't then the changes will be removed when you perform an automatic theme update.
We'd love to get some feedback to help us create better themes.
