+
+All official release packages are published to the official and public NuGet feed.
+
+Nightly builds (pre-release builds from the `develop` branch) produce unofficial pre-release NuGet packages which can be pulled from the project's public NuGet feed on GitHub:
+
+```
+https://github.com/orgs/giraffe-fsharp/packages
+```
+
+These packages are being tagged with the Workflow's run number as the package version.
+
+All other builds, such as builds triggered by pull requests produce a NuGet package which can be downloaded as an artifact from the individual GitHub action.
