+## Release Process
+
+Releases are created via GitHub Actions and include:
+
+1. Tag pushed (`v*.*.*`) triggers release workflow
+2. Tests run across supported Python versions
+3. Packages built (wheel and sdist)
+4. Docker images pushed to `ghcr.io/weekmo/routing-table-api`
+5. GitHub Release created with artifacts and notes
+
+To create a release locally:
+
+```bash
+git tag -a v1.0.0 -m "Release v1.0.0"
+git push origin v1.0.0
+```
+
+For container deployments, CI publishes images to GitHub Container Registry. Use pinned tags in production (for example `ghcr.io/weekmo/routing-table-api:v1.0.0`) instead of `:latest` and set `imagePullPolicy` accordingly.
