Router packages
The Stella Ops Router is a set of NuGet packages. A microservice author uses the client SDK and a client transport; a gateway operator runs the gateway tool or builds a gateway host from the gateway libraries and the server transports. This page lists which package serves which role and under which licence.
Install
Every package of a release is installed from the Stella Ops NuGet feed, https://nuget.stella-ops.org/v3/index.json. Versions have the form x.y.z-yyyyMMddTHHmmssZ: the UTC timestamp is the release’s first publication, and NuGet treats the form as a prerelease, so an install names the version or passes --prerelease:
dotnet add package StellaOps.Microservice --prerelease
Every Router package of one release shares one version, built from one commit; install the Router packages of one version together. The consumer rules (feed, version form, verifying a package) are in the NuGet library release guide.

Licences
Each package carries its licence file (LICENSE) and notice (NOTICE) and names its licence in its package metadata.
