# Audiobookshelf

Self-hosted audiobook and podcast server with progress sync across devices.

- Web UI: http://localhost:13378
- Audiobooks: \`$AUDIOBOOKS_PATH\` → mounted at /audiobooks
- Podcasts: \`podcasts/\` in this folder → /podcasts (change \`PODCASTS_PATH\` in .env)
- App data: \`config/\` and \`metadata/\`

## Manage
\`\`\`bash
cd $ABS_DIR
docker compose up -d      # start
docker compose down       # stop
docker compose logs -f    # logs
docker compose pull && docker compose up -d   # update
\`\`\`

First launch: open the web UI, create your admin account, then add libraries
pointing at /audiobooks and /podcasts.
