Framework systems, such as Drupal, Joomla,
Wordpress, Bootstrap, or other current technologies
may be used; however, pre-built templates and
themes for these sites are not permissible. If a
framework system is used, a statement affirming
that the template or theme used on the framework
was built by the team must be posted on an “About”
section or page.

Template engine websites, tools, and sites that
generate HTML from text, markdown, or script files,
such as Webs, Wix, Weebly, GitHub, Jekyll, and Replit,
are NOT permitted
