+## Building
+
+Images can be build locally if needed:
+
+```sh
+python build_image.py <image-name> <Dockerfile path>
+```
+
+CI will also build images when a tag of the format `v*` is pushed. The images built by CI are tagged as `:latest` and pushed to the registry at the run.
+
+If CI workflows are triggered manually (i.e. via `workflow_dispatch`), then the image push is skipped.
