 ## Docker Images
 
-Docker images are hosted on [docker.openmodelica.org](docker.openmodelica.org) and need to
-be uploaded manually.
+The images OpenModelica is built in, `build-deps`, come from the
+[build-deps] repository, whose CI builds them for each distribution and publishes them to
+`ghcr.io/openmodelica/build-deps` and `docker.openmodelica.org/build-deps`. They used to
+be built by hand from `Dockerfile.build-deps*` here.
 
-### Example
+The Dockerfiles still in [`docker/`](./docker) are for other, older images. Each has a
+script next to it that builds and pushes it, e.g. [`nightly.sh`](./docker/nightly.sh)
+for [`Dockerfile.nightly`](./docker/Dockerfile.nightly).
 
-To add a new image to [docker.openmodelica.org](docker.openmodelica.org)
-the image needs to be build, tagged correctly and then pushed to the server.

-For example for [Dockerfile.build-deps-cmake-1.16.3](./docker/Dockerfile.build-deps-cmake-1.16.3)
-one would run:
-
-```bash
-docker build --tag build-deps-cmake:v1.16.3 -f Dockerfile.build-deps-cmake-1.16.3 .
-docker tag build-deps-cmake:v1.16.3 docker.openmodelica.org/build-deps-cmake:v1.16.3
-docker push docker.openmodelica.org/build-deps-cmake:v1.16.3
