+## Installing as a NuGet Package
+
+The client publishes to the internal Gitea NuGet feed at
+`https://gitea.dohertylan.com/api/packages/dohertj2/nuget/index.json`.
+
+Add the feed once:
+
+````bash
+dotnet nuget add source https://gitea.dohertylan.com/api/packages/dohertj2/nuget/index.json \
+    --name dohertj2-gitea \
+    --username <gitea-username> \
+    --password <gitea-token-or-password> \
+    --store-password-in-clear-text
+````
+
+Then add the package to your project:
+
+````bash
+dotnet add package ZB.MOM.WW.MxGateway.Client --version 0.1.0
+````
+
+The `ZB.MOM.WW.MxGateway.Contracts` package is pulled in transitively.

+## Installing the Go client
+
+The module is resolved directly from the git repo — no package registry:
+
+````bash
+go get gitea.dohertylan.com/dohertj2/mxaccessgw/clients/go@v0.1.0
+````
+
+Then import:
+
+````go
+import "gitea.dohertylan.com/dohertj2/mxaccessgw/clients/go/mxgateway"
+````
+
+If your build environment cannot reach `gitea.dohertylan.com` directly,
+configure `GOPROXY` to point at an internal proxy that fronts the Gitea
+repo, or use `GONOSUMCHECK` + `GOPRIVATE` to bypass the checksum database
+for the internal module path.
+
+## Releasing a new version
+
+Go modules in monorepo subdirectories use prefixed tags. To tag a release
+from this repo:
+
+````bash
+pwsh scripts/tag-go-module.ps1 -Version v0.1.1 -Push
+````
+
+The script validates semver, refuses to tag with uncommitted tracked
+changes, creates an annotated tag `clients/go/v0.1.1`, and (with `-Push`)
+pushes it to origin.

+#Requires -Version 7
+
+<#
+.SYNOPSIS
+    Packs all MxAccessGateway clients into a single dist/ directory.
+
+.DESCRIPTION
+    Runs each language client's native packaging command:
+      .NET    -> dotnet pack (NuGet)
+      Python  -> python -m build (sdist + wheel)
+      Rust    -> cargo package (.crate)
+      Java    -> gradle assemble + jars (jar + sources + javadoc + pom)
+      Go      -> skipped; use scripts/tag-go-module.ps1
+
+    All artifacts land in -OutputDir (default: dist/).
+
+    With -Publish, each language pushes its package to the internal Gitea
+    feed. Requires GITEA_USERNAME and GITEA_TOKEN env vars.
+
+.PARAMETER OutputDir
+    Where to drop the packed artifacts. Default: ./dist
+
+.PARAMETER Languages
+    Subset of languages to pack. Default: all five.
+    Values: dotnet, python, rust, java, go
+
+.PARAMETER Publish
+    After packing, upload to Gitea feeds. Requires:
+      GITEA_USERNAME
+      GITEA_TOKEN
+    Will refuse to publish if either is missing.
+
+.PARAMETER SkipTests
+    Skip per-language regression tests before packing. Default: false.
+

+.SYNOPSIS
+    Tags a release of the Go MxAccessGateway client module.
+
+.DESCRIPTION
+    Go modules in monorepo subdirectories use prefixed tags
+    ("clients/go/v0.1.0") so `go get <module>@v0.1.0` resolves correctly.
+    This script validates the version, creates the prefixed tag at HEAD,
+    and (optionally) pushes it.
+
+.PARAMETER Version
+    Semver tag without the prefix, e.g. "v0.1.0".
+
+.PARAMETER Push
+    When set, pushes the tag to origin after creation.
+
+.EXAMPLE
+    pwsh scripts/tag-go-module.ps1 -Version v0.1.0
+    pwsh scripts/tag-go-module.ps1 -Version v0.1.1 -Push
