+# NBA Logo Downloader
+
+This script downloads all NBA team logos from the ESPN API and saves them in the `assets/sports/nba_logos/` directory for use with the NBA leaderboard.
+
+## Usage
+
+### Basic Usage
+```bash
+python download_nba_logos.py
+```
+
+### Force Re-download
+If you want to re-download all logos (even if they already exist):
+```bash
+python download_nba_logos.py --force
+```
+
+### Quiet Mode
+Reduce logging output:
+```bash
+python download_nba_logos.py --quiet
+```
+
+### Combined Options
+```bash
+python download_nba_logos.py --force --quiet
+```
+
+## What It Does
+
+1. **Fetches NBA Team Data**: Gets the complete list of NBA teams from ESPN API
+2. **Downloads Logos**: Downloads each team's logo from ESPN's servers
+3. **Saves Locally**: Saves logos as `{team_abbr}.png` in `assets/sports/nba_logos/`
+4. **Skips Existing**: By default, skips teams that already have logos
+5. **Rate Limiting**: Includes small delays between downloads to be respectful to the API
+
+## Expected Output
+
+```
+🏀 Starting NBA logo download...
+Target directory: assets/sports/nba_logos/
+Force download: False
+✅ NBA logo download complete!
+📊 Summary: 30 downloaded, 0 failed
+🎉 NBA logos are now ready for use in the leaderboard!

+## Integration with NBA Leaderboard
+
+Once the logos are downloaded, the NBA leaderboard will:
+- ✅ Use local logos instantly (no download delays)
+- ✅ Display team logos in the scrolling leaderboard
+- ✅ Show proper team branding for all 30 NBA teams
+
+## Troubleshooting
+
+### "Import error: No module named 'requests'"
+Make sure you're running this from the LEDMatrix project directory where all dependencies are installed.
+
+### "Permission denied" errors
+Make sure the script has write permissions to the `assets/sports/nba_logos/` directory.
+
+### Some logos fail to download
+This is normal - some teams might have temporary API issues or the ESPN API might be rate-limiting. The script will continue with the successful downloads.
+
+## Requirements
+
+- Python 3.7+
+- `requests` library (should be installed with the project)
+- Write access to `assets/sports/nba_logos/` directory
