+# MediaLore
+
+A self-hosted web UI for browsing media libraries on a NAS or local filesystem. Configure folders as typed libraries — currently supporting **Games** and **Mixed Media** library types.
+
+## Features
+
+- **Games library** — displays a grid of game cover art scanned from folders. Each game folder is expected to contain a `.zip` archive and optional artwork (`cover.*`, `widecover.*`). Clicking a game opens a detail modal with a download link for the zip.
+- **Mixed media library** — a folder-navigable browser that mirrors the directory structure on disk. Videos open in an inline player (with full seek support via HTTP range requests). Images open in a lightbox. Other files are opened in a new tab.
+- **Configurable libraries** — libraries are registered in `libraries.json` at the project root; no database required.
+- **Path-jailed file serving** — all file access is verified to stay within the configured library root before being served.

+
+## Developer Setup
+
+**Requirements:** Node.js 18+
+
+```bash
+# 1. Install dependencies
+npm install
+
+# 2. Start the development server
+npm run dev
+```
+
+Open [http://localhost:3000](http://localhost:3000).
+
+Other available commands:
+
+```bash
+npm run build   # Production build
+npm run start   # Start production server (run build first)
+npm run lint    # Run ESLint
+```
+
+## Library Configuration
+
+Libraries are defined in `libraries.json` at the project root:
+
+```json
+[
+  {
+    "id": "games",
+    "name": "Games",
+    "path": "./data/Games",
+    "type": "games"
+  },
+  {
+    "id": "various",
+    "name": "Various Media",
+    "path": "./data/Various Media",
+    "type": "mixed"
+  }
+]
+```
+
+| Field  | Description |
+|--------|-------------|
+| `id`   | URL-safe unique identifier used in routes (`/library/<id>`) |
+| `name` | Display name shown in the UI |
+| `path` | Absolute or project-relative path to the library root folder |
+| `type` | `"games"` or `"mixed"` |
+
+Paths can point anywhere on the filesystem — they do not need to be inside the project directory. Restart the dev server after editing `libraries.json`.
+
+## Library Folder Conventions
+
+### Games (`"type": "games"`)
+
+Each game is a subdirectory containing:
+
+```
+Games/
+└── My Game Title/
+    ├── My Game Title.zip   # Required — the downloadable archive
+    ├── cover.png           # Optional — portrait cover art (case-insensitive)
+    └── widecover.jpg       # Optional — landscape/hero cover art (case-insensitive)
+```
+
+- The `.zip` filename can be anything; the first `.zip` found in the folder is used.
+- Cover art filenames are matched case-insensitively against `cover.*` and `widecover.*`. Any image extension is accepted.
+
+### Mixed Media (`"type": "mixed"`)
+
+No specific structure is required. The UI mirrors the directory tree exactly as it exists on disk. Supported media types:
+
+- **Video:** `.mp4`, `.mov`, `.mkv`, `.avi`, `.webm`, `.m4v`
+- **Image:** `.jpg`, `.jpeg`, `.png`, `.gif`, `.webp`, `.bmp`, `.tiff`
+
+## API Reference
+
+All API routes are server-side. File paths are never exposed in client-side state — only opaque `/api/file?...` URLs are sent to the browser.
+
+| Route | Method | Description |
+|-------|--------|-------------|
+| `/api/libraries` | GET | Returns the full library list from `libraries.json` |
+| `/api/games?libraryId=<id>` | GET | Scans the games library and returns structured game entries |
+| `/api/browse?libraryId=<id>&path=<subpath>` | GET | Lists the contents of a directory within a mixed library |
+| `/api/file?libraryId=<id>&path=<relpath>` | GET | Streams a file; supports HTTP `Range` requests for seekable video playback |
