+# GitHub Workflows for open-vmdk
+
+This directory contains GitHub Actions workflows for building, testing, and releasing Debian packages for open-vmdk.
+
+## Workflows
+
+### 1. `debian-build-test.yml` - Build and Test Debian Packages
+
+**Triggers:**
+- Push to `main` or `master` branch
+- Pull requests to `main` or `master` branch  
+- Manual workflow dispatch
+
+**What it does:**
+- Builds Debian packages on multiple Ubuntu versions (20.04, 22.04, 24.04)
+- Handles fakeroot issues by falling back to manual build method
+- Tests package installation and basic functionality
+- Runs lintian quality checks
+- Uploads built packages as artifacts
+
+**Matrix strategy:** Tests on Ubuntu 20.04, 22.04, and 24.04
+
+### 2. `multi-arch-test.yml` - Multi-Architecture Package Test
+
+**Triggers:**
+- Push to `main` or `master` branch
+- Push of version tags (`v*`)
+- Pull requests to `main` or `master` branch
+- Manual workflow dispatch
+
+**What it does:**
+- Builds and tests packages on multiple architectures (amd64, arm64)
+- Uses Docker with QEMU for cross-architecture testing
+- Verifies packages work correctly on different CPU architectures
+- Uploads packages from amd64 build as artifacts
+
+### 3. `release.yml` - Create Release Packages
+
+**Triggers:**
+- Push of version tags (`v*`)
+- Manual workflow dispatch with tag input
+
+**What it does:**
+- Builds release-quality Debian packages
+- Updates changelog with release version and date
+- Runs quality checks with lintian
+- Creates SHA256 checksums for packages
+
+## Usage
+
+### For Development
+
+The build and test workflows run automatically on every push and pull request, ensuring packages build correctly across different environments.
+
+### Downloading Artifacts
+
+Built packages are available as workflow artifacts:
+- Go to the Actions tab
+- Click on a completed workflow run
+- Download the "debian-packages-*" artifacts
+
+## Environment Handling
+
+The workflows handle common build environment issues:
+
+- **Fakeroot problems:** Automatically falls back to manual build using sudo
+- **Multi-architecture:** Uses QEMU for cross-compilation testing
+- **Dependency resolution:** Installs all required build and runtime dependencies
+- **Permission fixes:** Ensures proper file ownership after sudo operations
+
+## Package Testing
+
+Each workflow includes comprehensive testing:
+
+1. **Build verification:** Ensures packages build successfully
+2. **Content verification:** Checks package contents and metadata
+3. **Installation testing:** Installs packages and resolves dependencies
+4. **Functionality testing:** Tests that installed binaries work
+5. **Configuration testing:** Verifies config files and directories are created
+6. **Quality checks:** Runs lintian for Debian policy compliance
+
+## Artifacts and Releases
+
+- **Development builds:** Available as workflow artifacts (30-day retention)
+- **Release builds:** Attached to GitHub releases with checksums
+- **Build logs:** Available as artifacts when builds fail (7-day retention)
+
+## Troubleshooting
+
+If workflows fail:
+
+1. Check the workflow logs for specific error messages
+2. Common issues:
+   - Dependency installation failures
+   - Fakeroot/permission issues (handled automatically)
+   - Network timeouts during package downloads
+   - Architecture-specific build failures
+
+3. Build logs and artifacts are preserved for debugging
+
+## Customization
+
+To customize the workflows:
+
+- **Add new test platforms:** Modify the matrix strategy in `debian-build-test.yml`
+- **Change retention periods:** Adjust `retention-days` in upload-artifact steps
+- **Add new architectures:** Extend the arch matrix in `multi-arch-test.yml`
+- **Modify release format:** Update the release body template in `release.yml`
