 All of the Node.js Foundation websites, including this repo, are jointly governed by the **Website Working Group**. See [GOVERNANCE.md](./GOVERNANCE.md) to learn more about the group's structure and [CONTRIBUTING.md](./CONTRIBUTING.md) for guidance about the expectations for all contributors to this project.
 
+### Content vs. Code
+
+The Website Working Group is primarily concerned with the code and overall structure of the website.
+
+The content of the website comes from a variety of working groups (Evangelism, Core, i18n, etc). 
+The Website WG defers to these WGs on matters of content and routinely adds collaborators from these
+working groups as they add and improve content on the website. In other words, the Website WG is not
+and *editorial* Working Group except when no other Working Group has taken responsibility for a
+content area.
