+# MetaMesh Plugin: TMDB
+
+A MetaMesh plugin that fetches metadata from The Movie Database (TMDB) API.
+
+## Description
+
+This plugin enriches video metadata by querying the TMDB API:
+
+- **Search by IMDB ID**: Uses existing IMDB ID for precise matching
+- **Search by title**: Falls back to title/year search
+- **Image download**: Downloads poster and backdrop images to `/files/poster/`
+- **Rich metadata**: Fetches plot, rating, genres, studios
+
+**Note**: This runs on the background queue as it makes external API calls.
+
+## Metadata Fields
+
+| Field | Description |
+|-------|-------------|
+| `tmdbid` | TMDB ID |
+| `imdbid` | IMDB ID |
+| `title` | Localized title |
+| `originalTitle` | Original title |
+| `movieYear` | Release year |
+| `releasedate` | Full release date |
+| `rating` | Vote average |
+| `plot/eng` | English plot synopsis |
+| `poster` | Poster image CID |
+| `posterPath` | Poster file path |
+| `backdrop` | Backdrop image CID |
+| `backdropPath` | Backdrop file path |
+| `genres` | Genre set |
+| `studio` | Production company set |
+
+## Dependencies
+
+- Requires `file-info`, `filename-parser`, and `jellyfin-nfo` plugins
+
+## Configuration
+
+| Field | Type | Required | Description |
+|-------|------|----------|-------------|
+| `apiKey` | string | Yes | TMDB API key or v4 bearer token |
+| `language` | select | No | Metadata language (default: en-US) |
+
+## API Endpoints
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/health` | GET | Health check |
+| `/manifest` | GET | Plugin manifest |
+| `/configure` | POST | Update configuration (API key) |
+| `/process` | POST | Process a file |
+
+## Running Locally
+
+```bash
+npm install
+npm run build
+npm start
+```
+
+## Docker
+
+```bash
+docker build -t metamesh-plugin-tmdb .
+docker run -p 8080:8080 metamesh-plugin-tmdb
+```
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PORT` | `8080` | HTTP server port |
+| `HOST` | `0.0.0.0` | HTTP server host |
+| `FILES_PATH` | `/files` | Base path for image downloads |
