+## Publishing
+
+### GitHub
+
+Create release on tag done by VERSIONING.md process. It will trigger `maven-release.yml` workflow that
+will deploy Maven packages to GitHub Maven package repository.
+
+### Manual
+
+Since build uses `exists-maven-plugin` then `altDeploymentRepository` doesn't work as it only works 
+for `deploy` plugin. Set `project.distributionManagement` user properties instead:
+```
+mvn deploy -Dproject.distributionManagement.repository.id=github \
+-Dproject.distributionManagement.repository.url=https://maven.pkg.github.com/open-eid/cdoc2-java-ref-impl`
+```
