+# Photo Background Remover
+
+A simple Go program that captures a photo from your webcam and removes the background.
+
+## Prerequisites
+
+### 1. Install ffmpeg
+```bash
+# Ubuntu/Debian
+sudo apt install ffmpeg
+
+# macOS
+brew install ffmpeg
+```
+
+### 2. Install Docker
+```bash
+# Ubuntu/Debian
+sudo apt install docker.io
+
+# macOS
+brew install --cask docker
+```
+
+The program uses the `danielgatis/rembg` Docker container for background removal. The AI model (~176MB) will be downloaded automatically on first run.
+
+## Usage
+
+1. Build and run the program:
+```bash
+go run main.go
+```
+
+2. The program will:
+   - Capture a photo from your webcam
+   - Remove the background
+   - Save both images in the `output/` directory
+
+## Output
+
+- `output/photo_TIMESTAMP.jpg` - Original photo
+- `output/photo_TIMESTAMP_nobg.png` - Photo with background removed
+
+## Troubleshooting
+
+- **Webcam not found**: Make sure `/dev/video0` exists (Linux) or adjust the device in the code
+- **ffmpeg not found**: Install ffmpeg using the commands above
+- **Docker not found**: Install Docker using the commands above
+- **Docker permission denied**: Add your user to the docker group: `sudo usermod -a -G docker $USER` (then log out and back in)
+- **Webcam permission denied**: You may need to add your user to the `video` group: `sudo usermod -a -G video $USER`
