+# MetaMesh Plugin: Jellyfin NFO
+
+A MetaMesh plugin that parses Jellyfin/Kodi NFO metadata files.
+
+## Description
+
+This plugin parses XML-based NFO metadata files used by Jellyfin, Kodi, and other media managers. It extracts:
+
+- **Movie/TV show metadata**: title, year, rating, plot
+- **External IDs**: IMDB, TMDB, AniDB
+- **Categories**: genres, studios, tags
+
+The plugin looks for:
+- `{filename}.nfo` - File-specific metadata
+- `tvshow.nfo` - Series-level metadata in the same directory
+
+## Metadata Fields
+
+| Field | Description |
+|-------|-------------|
+| `videoType` | `movie` or `tvshow` |
+| `originalTitle` | Original title from NFO |
+| `season` | Season number |
+| `episode` | Episode number |
+| `movieYear` | Release year |
+| `rating` | User rating |
+| `imdbid` | IMDB ID |
+| `tmdbid` | TMDB ID |
+| `anidbid` | AniDB ID |
+| `plot/{lang}` | Plot description (language detected) |
+| `genres` | Genre set |
+| `studio` | Production studio set |
+| `tags` | Tag set |
+
+## Dependencies
+
+- Requires `file-info` and `filename-parser` plugins
+
+## Configuration
+
+No configuration required.
+
+## API Endpoints
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/health` | GET | Health check |
+| `/manifest` | GET | Plugin manifest |
+| `/configure` | POST | Update configuration |
+| `/process` | POST | Process a file |
+
+## Running Locally
+
+```bash
+npm install
+npm run build
+npm start
+```
+
+## Docker
+
+```bash
+docker build -t metamesh-plugin-jellyfin-nfo .
+docker run -p 8080:8080 metamesh-plugin-jellyfin-nfo
+```
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PORT` | `8080` | HTTP server port |
+| `HOST` | `0.0.0.0` | HTTP server host |
