+# Docker Setup and GitHub Packages Release
+
+## Docker Build
+
+Build the Docker image:
+
+```bash
+docker build -t xcstrings-translator .
+```
+
+## Running the Container
+
+Run the container with your xcstrings files:
+
+```bash
+# Mount a directory containing your xcstrings files
+docker run -v /path/to/your/files:/workspace -w /workspace xcstrings-translator [command] [options]
+
+# Example:
+docker run -v $(pwd):/workspace -w /workspace xcstrings-translator google --api-key "your-key" --input "Localizable.xcstrings" --target-languages "zh-Hans"
+```
+
+## GitHub Packages Release
+
+The Docker image is automatically built and pushed to GitHub Container Registry when you push to the main branch or create a tag.
+
+### Manual Release Process
+
+1. **Build and tag the image:**
+```bash
+# Get the current version from cmd/root.go or create a tag
+VERSION=$(grep 'Version = ' cmd/root.go | cut -d'"' -f2)
+docker build -t ghcr.io/fdddf/xcstrings-translator:${VERSION} .
+docker tag ghcr.io/fdddf/xcstrings-translator:${VERSION} ghcr.io/fdddf/xcstrings-translator:latest
+```
+
+2. **Login to GitHub Container Registry:**
+```bash
+echo $GITHUB_TOKEN | docker login ghcr.io -u USERNAME --password-stdin
+```
+
+3. **Push the image:**
+```bash
+docker push ghcr.io/fdddf/xcstrings-translator:${VERSION}
+docker push ghcr.io/fdddf/xcstrings-translator:latest
+```
+
+### Automated Release with GitHub Actions
+
+The workflow in `.github/workflows/docker-release.yml` automatically:
+- Builds the Docker image on pushes to main branch
+- Tags images with branch names, PR numbers, semantic versions, and commit SHAs
+- Pushes to GitHub Container Registry
+- Runs security scanning with Trivy
+
+#### Workflow Triggers:
+- Push to `main` or `master` branches
+- Push of version tags (`v*`)
+- Pull requests to `main`
+
+### Using the Released Image
+
+Pull and run the latest image:
+
+```bash
+docker pull ghcr.io/fdddf/xcstrings-translator:latest
+docker run ghcr.io/fdddf/xcstrings-translator:latest --help
+```
+
+## Multi-platform Support
+
+The GitHub Actions workflow builds for both `linux/amd64` and `linux/arm64` architectures.
+
+## Security Features
+
+- Runs as non-root user (UID 65532)
+- Minimal Alpine base image
+- Health checks built-in
+- Built with security scanning via Trivy
