About this manual ​

This manual covers Raylux: the Nexus service, and the three client programs that connect to it:

You are reading this from Nexus itself, at /manual. It is installed alongside Nexus and works with no internet connection.

Version

This manual is built and shipped with Nexus, so it always describes the version you have installed — the badge at the top of every page names it. The running Nexus's own version shows in ConfigHub's top bar next to the gateway name (e.g. "Raylux 2026.12") once you are signed in — it is not shown to an anonymous visitor. From the command line, run raylux-nexus --version.
