- Changed project title and tagline in docusaurus.config.js to reflect the new branding.
- Updated package.json and package-lock.json to rename the project to gregwiki-docs-site.
- Adjusted sidebar and documentation files to align with the new project structure and naming conventions.
- Enhanced documentation content for clarity and consistency across various sections.
- Added Prettier as a development dependency for code formatting.

+# Framework plugins (`FFM.Plugin.*`)
+
+These **plugins** ship as `FFM.Plugin.*` assemblies and extend the **framework runtime**. They are deployed under the game’s FMF plugin path (see [Game folder layout](/wiki/topics/meta/game-folder-layout)).
+
+Gameplay mods (`FMF.*`) are documented under **[Mods](../mods/index)** — not here.
