 ## To update
 
-Update the Dockerfile, tag the commit with `tagname`, git push, then build and push the docker container:
-
-```bash
-docker build . -t ghcr.io/spatial-model-editor/manylinux_x86_64:tagname
-docker push ghcr.io/spatial-model-editor/manylinux_x86_64:tagname
-```
-
-where `tagname` is today's date in the form `YYYY.MM.DD`
-
-## Note
-
-Would be cleaner to have a github action that builds the container on each tagged commit, as we do for sme_deps etc.
-
-Currently not doing this for convenience, as the docker build would take a long time to run on CI.
+To release new images, tag the commit with `YYYY.MM.DD`
