+# GitHub Actions Workflows
+
+## Docker Multi-Architecture Build
+
+This repository now uses GitHub Actions to build Docker images with multi-architecture support (AMD64 and ARM64).
+
+### Migration from Travis CI
+
+- **Before**: Travis CI built single-architecture images only
+- **After**: GitHub Actions builds both AMD64 and ARM64 architectures
+
+### Required Secrets
+
+Configure these secrets in the repository settings:
+
+- `DOCKER_USERNAME`: Docker Hub username
+- `DOCKER_PASSWORD`: Docker Hub access token
+
+### Build Triggers
+
+- **Push to master**: Builds and publishes all image variants
+- **Pull requests**: Builds images for testing (no push)
+- **Weekly schedule**: Rebuilds to catch upstream Node.js updates
+
+### Supported Architectures
+
+All images now support:
+- `linux/amd64` (Intel/AMD 64-bit)
+- `linux/arm64` (ARM 64-bit, including Apple Silicon)
+
+### Matrix Strategy
+
+The workflow builds all combinations of:
+- Node versions: 18, 20, 22, 24, latest
+- Variants: alpine, bookworm, bullseye, buster, slim
+
+Some combinations are excluded for compatibility reasons (e.g., buster with Node 22+).
