+## Releasing
+
+New versions publishing is very simple - just make required changes in this repository, update [changelog file](CHANGELOG.md) and "publish" new release using repo releases page.
+
+Docker images will be build and published automatically.
+
+> New release will overwrite the `latest` docker image tag in both registers.
