XBUSX — user guide

This guide is a stub. Content is coming as the docs settle.

Things this guide will cover:

• Connecting an I/K-Bus interface (DIY hardwire tap vs USB adapter).
• Live-monitoring telegrams with the CLI / TUI / web app.
• Filtering by source, destination, or message type.
• Replaying logged captures.
• Sending commands to specific devices (steering-wheel buttons, IKE display lines, GM comfort triggers).

In the meantime, the project README has the quick-start.
