-   dotnet build tests/IntervalTree.Net.Tests/IntervalTree.Net.Tests.csproj --configuration Release --no-restore

 ## Build and Test Instructions
 
-- **Building**: Use `dotnet build tests/IntervalTree.Net.Tests/IntervalTree.Net.Tests.csproj --configuration Release` to compile the library and test project.  The library project includes no external dependencies.
-- **Testing**: All new features must include unit tests.  Tests should be added to the existing xUnit project under `tests/IntervalTree.Net.Tests/`.  Run `dotnet test tests/IntervalTree.Net.Tests/IntervalTree.Net.Tests.csproj --configuration Release` to execute the test suite.
-- **Continuous Integration**: No GitHub Actions workflow is currently configured.  Run restore, build and test locally before requesting a review.
+- **Building**: Use `dotnet build IntervalTree.Net.sln --configuration Release` to compile the library and test project.  The library project includes no external dependencies.
+- **Testing**: All new features must include unit tests.  Tests should be added to the existing xUnit project under `tests/IntervalTree.Net.Tests/`.  Run `dotnet test IntervalTree.Net.sln --configuration Release` to execute the test suite.
+- **Package validation**: Use `dotnet pack src/IntervalTree.Net/IntervalTree.Net.csproj --configuration Release --no-build` to create a local package for inspection.  Do not publish packages from local validation.
+- **Continuous Integration**: Pull requests and pushes to `master` run restore, build, test and pack validation.  The workflow does not publish packages or require secrets.
