 A Jellyfin plugin that adds podcast support to your media server.
 
+## Quick Install
+
+Add this repository URL in Jellyfin (Dashboard → Plugins → Repositories):
+
+```
+https://gitea.tourolle.paris/dtourolle/jellypod/raw/branch/master/manifest.json
+```
+
 ## Features
 
 - Browse and subscribe to podcasts
 - Automatic episode downloads
 - Integration with Jellyfin's library system
+- Post-download script hook for audio processing
+
+## Post-Download Script Hook
+
+Jellypod supports running a custom script on each downloaded episode before it's added to your library. This is useful for:
+
+- Audio normalization (e.g., using ffmpeg-normalize)
+- Format conversion
+- Metadata enhancement
+- Custom processing workflows
+
+### Configuration
+
+In the plugin settings (Dashboard → Plugins → Jellypod):
+
+1. **Post-Download Script Path**: Full path to your script or executable
+2. **Script Timeout**: Maximum execution time in seconds (default: 60)
+
+### Script API
+
+Your script will be called with two arguments:
+
+```bash
+script <input_file> <output_file>
+```
+
+- `input_file`: Path to the downloaded episode (read-only)
+- `output_file`: Path where your script should write the processed file
+
+### Example Scripts
+
+**Audio normalization (bash + ffmpeg):**
+```bash
+#!/bin/bash
+INPUT="$1"
+OUTPUT="$2"
+ffmpeg-normalize "$INPUT" -o "$OUTPUT" -c:a libmp3lame -b:a 128k
+```
+
+**Format conversion (bash + ffmpeg):**
+```bash
+#!/bin/bash
+INPUT="$1"
+OUTPUT="$2"
+ffmpeg -i "$INPUT" -c:a aac -b:a 128k "$OUTPUT"
+```
+
+### Behavior
+
+- If the script succeeds (exit code 0) and creates the output file, the processed file is added to your library
+- If the script fails, times out, or doesn't create an output file, the original downloaded file is used instead
+- All script output (stdout/stderr) is logged for debugging
+- Leave the script path empty to disable post-processing
