+# MetaMesh Plugin: Filename Parser
+
+A MetaMesh plugin that parses video filenames to extract metadata like title, season, episode, and year.
+
+## Description
+
+This plugin analyzes video filenames using the `@metazla/filename-tools` library to extract structured metadata. It handles various naming conventions including:
+
+- Movies: `Movie Title (2024).mkv`
+- TV Shows: `Show.S01E05.Episode.Name.mkv`
+- Anime: `[Group] Title - 01 [1080p].mkv`
+
+## Metadata Fields
+
+| Field | Description |
+|-------|-------------|
+| `originalTitle` | Extracted title from filename |
+| `videoType` | `movie` or `tvshow` |
+| `season` | Season number (TV shows) |
+| `episode` | Episode number (TV shows) |
+| `movieYear` | Release year |
+| `increment` | Episode increment |
+| `extra` | Extra info (e.g., "Director's Cut") |
+
+## Dependencies
+
+- Requires `file-info` plugin to run first
+
+## 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-filename-parser .
+docker run -p 8080:8080 metamesh-plugin-filename-parser
+```
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `PORT` | `8080` | HTTP server port |
+| `HOST` | `0.0.0.0` | HTTP server host |
+
