## Common questions

### Why does a fresh Linux package install not start NZBfast?

The package enables the service for the next boot, but a fresh install does not start it until a Usenet provider is configured. Add the provider before expecting the app to run.

### Can Sonarr, Radarr, or similar tools connect without custom API changes?

Yes. NZBfast speaks the SABnzbd and NZBGet APIs, so Sonarr, Radarr, nzb360, and LunaSea connect unmodified.

### Does NZBfast include an indexer?

Yes, it includes a built-in indexer.

### Do I need separate PAR2 repair and archive extraction programs?

No, repair and unpack tools are built into the executable.

### Do RAR archive volumes remain on disk before extraction?

No, the archive is extracted during download, so RAR volumes do not exist as files.
