Not everything worth knowing about Joomla fits into a task-based section. This is background knowledge: the legal footing the project stands on, and some fundamentals of how the web works that explain why Joomla behaves the way it does.

  • Joomla Licenses – Joomla is released under the GNU General Public Licence; a look at what that licence covers.
  • Joomla! Copyright – How copyright works in the Joomla project: contributors keep copyright on their own code, licensed under GNU/GPL, while Open Source Matters holds the project's collective assets.
  • What are web standards? – What web standards are, why they matter for compatibility and avoiding vendor lock-in, and the World Wide Web Consortium's role in defining them.
  • Where are the web pages? – Why you won't find your content as separate HTML files: Joomla stores pages as database records and assembles them dynamically when a visitor requests them.
