====== Single-file direct upload ======
This guide covers the current verified ApuClient flow. It uploads one file directly to the NAS; the cloud service is used for discovery and pairing only.

===== Before you begin =====
* The NAS must be online and the ApuSync service enabled.
* The client must trust the configured service certificate and verify the NAS identity.
* The NAS owner must select a writable destination and approve the client public key.

===== Upload =====
1. Open the client and enter the short pairing code shown by the NAS.
2. Confirm the NAS identity and wait for the owner approval.
3. Sign in with the NAS account when the verified channel is ready.
4. Select one file. The current release accepts files up to 64 MiB.
5. Keep the page open until the NAS confirms the committed size and SHA-256.

If the browser is closed or the connection drops, the current release requires pairing again and restarts the file. Automatic photo scanning, directory jobs, scheduled backups and persistent resume are separate future capabilities.
