After installing

Pair the device. The agent opens your browser with a short code. Sign in, choose a workspace and approve. The agent appears in the tray and in Devices.

Subscribe. In a new terminal run hashrelay subscribe #builds, or add tags from the Devices page.

Test it. Run hashrelay test. A notification should appear in Windows Notification Center within a second.

Requirements

Windows 10 version 1809 or later, or Windows 11, 64-bit.
No .NET install needed: the agent and CLI are self-contained.
Outbound HTTPS to hashrelay.dev.avlon.ca (WebSockets preferred, long-polling fallback).

The installer is not yet code-signed; Windows SmartScreen may ask you to confirm the first run.
