 To properly test and run this project, you will need to prepare your environment:
 
-1. **Install Node.js & FFmpeg**:
+1. **Install Node.js**:
    - Ensure Node.js (v18+) is installed.
-   - Install **FFmpeg** on your system and make sure it is available in your PATH environment variable. The Node.js library `fluent-ffmpeg` requires it.
+   - The project uses npm-provided `ffmpeg-static` and `ffprobe-static` binaries by default, so you do not need to install FFmpeg globally.
+   - If you want to override the bundled binaries, set `FFMPEG_PATH` and `FFPROBE_PATH` in your environment.
 
 2. **AWS S3 / MinIO Configuration**:
    - Modify the `.env` file (copy from `.env.example`).
