- 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.

 # Legacy wiki import
 
-All material under **`docs/wiki-import/`** is part of the **GitHub Wiki mirror**: it is meant to track the wiki that lives alongside the repository, while the rest of **`docs/`** holds **curated** pages (topics, mods, reference).

 ## Why this exists
 
 - **Search & versioning**: Wiki text is in Git, reviewable in PRs, and indexed by the site.
-- **i18n**: Paired `Page.md` (DE) + `Page-en.md` (EN) are split by `wiki:normalize-i18n` into the default locale and `wiki/i18n/de/...`.
+- **i18n**: Paired `Page.md` (DE) + `Page-en.md` (EN) are split by `wiki:normalize-i18n` into the default locale and `i18n/de/.../legacy/wiki-import/`.
 - **Sorting**: Audience trees (`EndUser/`, `ModDevs/`, `Contributors/`, `TechnicalReference/`, `DataCenterFAQ/`) use `_category_.json` **positions** so the sidebar order matches intent, not only A–Z. Root **`Home`** uses `sidebar_position: 1` so it appears first among loose pages.
 
 ## Keep the mirror up to date
 
-1. Clone or pull the wiki repo into **`.wiki/`** at the **repository root** (same level as `docs/`):
+1. Clone or pull the wiki repo into **`.wiki/`** at **`gregFramework/`** (sibling to your repo clones):
 
    ```bash
    git clone https://github.com/<org>/<repo>.wiki.git .wiki
    ```
 
-2. From **`wiki/`** (the Docusaurus app):
+2. From **`gregWiki/`** (the Docusaurus app):
 
    ```bash
    npm run wiki:refresh
    ```
 
-   This runs **`wiki:sync`** (copy `.wiki` → `docs/wiki-import/`) and then **`wiki:normalize-i18n`**. If `.wiki` is missing, `wiki:sync` exits with an error; run `wiki:normalize-i18n` alone only when you are fixing splits without pulling the wiki.

 ## Editorial policy (recommended)
 
 | Goal | Action |
 |------|--------|
-| **Short-term fix** on the live site | Edit files under `docs/wiki-import/` (and DE mirror if applicable). Optionally backport to `.wiki` so the next sync does not overwrite you. |
-| **Canonical, long-term doc** | Add or move content into **`docs/topics/`**, **`docs/reference/`**, or **`docs/mods/`**, and link from the legacy page. |
