+# GitHub Actions Migration
+
+This PR adds GitHub Actions workflows to run alongside the existing Azure Pipelines configuration.
+
+## Files to Move
+
+Due to GitHub App permission restrictions, the workflow files are created in the root directory. Please move these files to `.github/workflows/` after merging:
+
+1. `github-actions-ci.yml` → `.github/workflows/ci.yml`
+2. `github-actions-pr.yml` → `.github/workflows/pr.yml`
+
+## Key Features
+
+### CI Workflow (ci.yml)
+- Triggers on pushes to master, release/*, and maintenance/* branches
+- Builds with .NET nanoFramework support using `nanoframework/nanobuild@v1` action
+- Runs tests and uploads coverage to codecov.io
+- Publishes NuGet packages to nuget.org (only on master branch)
+- Uses Windows runner to match Azure Pipelines configuration
+
+### PR Workflow (pr.yml)
+- Triggers on pull requests to master, release/*, and maintenance/* branches
+- Same build and test process as CI workflow
+- Publishes test results as PR checks
+- Uploads test coverage to codecov.io
+- No NuGet publishing for PRs
+
+## .NET nanoFramework Support
+
+The key challenge mentioned in the issue was .NET nanoFramework support. This is handled using the `nanoframework/nanobuild@v1` GitHub Action, which is the official GitHub Actions equivalent of the Azure Pipelines `InstallNanoMSBuildComponents@1` task.
+
+## Migration Notes
+
+- Both workflows use the existing PowerShell build script (`Build/build.ps1`) with the `-IncludeNanoFramework` flag
+- Secrets needed: `CODECOV_TOKEN` and `NUGET_ORG_APIKEY` (should already be configured)
+- The workflows are designed to run alongside Azure Pipelines for comparison
+- Azure Pipelines configuration files remain unchanged as requested
+
+## Next Steps
+
+1. Move the workflow files to `.github/workflows/`
+2. Test both workflows to ensure they work correctly
+3. Compare results with Azure Pipelines
+4. Make any necessary adjustments based on testing
