@ -30,6 +29,18 @@ Pingvin Share is self-hosted file sharing platform and an alternative for WeTran
The website is now listening available on `http://localhost:3000`, have fun with Pingvin Share 🐧!
### Integrations
#### ClamAV
With ClamAV the shares get scanned for malicious files and get removed if any found.
1. Add the ClamAV container to the Docker Compose stack (see `docker-compose.yml`) and start the container.
2. As soon as the ClamAV container is ready (when ClamAV logs "socket found, clamd started"), restart the Pingvin Share container with `docker compose restart pingvin-share`
3. The Pingvin Share logs should now log "ClamAV is active"
Please note that ClamAV needs a lot of [ressources](https://docs.clamav.net/manual/Installing/Docker.html#memory-ram-requirements).
### Additional resources
- [Synology NAS installation](https://mariushosting.com/how-to-install-pingvin-share-on-your-synology-nas/)
