 To run one of the provided microservices in this repo, the basic command is the following:
 ```
-docker run --rm -e MICROSERVICE=<name of microservice> ghcr.io/dune-daq/microservices:9685
+docker run --rm -e MICROSERVICE=<name of microservice> ghcr.io/dune-daq/microservices:develop
 ```
 
 There are a couple of points to note:
 * The value of MICROSERVICE should be the name of a given microservice's subdirectory in this repo. As of Oct-6-2023, the available subdirectories are: `config-service`, `ers-dbwriter`, `ers-protobuf-dbwriter`, `logbook`, `opmon-dbwriter`, `runnumber-rest` and `runregistry-rest`. 
 * Most microservices require additional environment variables to be set, which can be passed using the usual docker syntax: `-e VARIABLE_NAME=<variable value>`
 * If you don't know what these additional environment variables are, you can just run the `docker` command as above without setting them; the container will exit out almost immediately but only after telling you what variables are missing
-* The `9685` tag for the image in the example above just refers to the first four characters of the git commit of the microservices repo whose `dockerfiles/Dockerfile.microservices` Docker file was used to create the image. Currently [Dec-08-2023] this is the head of a branch soon to be merged in develop with a PR. 
+* The microservices image tag will be `microservices:<name-of-branch>` or `microservices:<version-tag>`, i.e. `microservices:develop`.
+* The microservices dependency image tag is `microservices_dependencies:<name-of-branch>` or `microservices_dependencies:<version-tag>`
 
 For details on a given microservice, look at its own README file (format is `docs/README_<microservice name>.md`). They may or may not be up to date, however.

-When building from a branch that is not develop you need to specify the branch you want to use to build the code, e.g.:
+## Building images
+There are two workflow actions on GitHub to build the `microservices` and `microservices_dependencies` images. This can be run on GitHub directly and will create the images, tag them and push them for use.
+
+The `microservices_dependencies` image is used as the base image for `microservies` and so any changes to the `requirements.txt` file requires rebuilding the `microservices_dependencies` image.
+
+If you do not wish to to push your changes to the repo when testing, you can also use:
+
 ```bash
-docker build -f Dockerfile.microservices -t ghcr.io/dune-daq/microservices:user-my-branch --build-arg BRANCH=my-branch .
+docker build -f Dockerfile -t ghcr.io/dune-daq/microservices:user-my-branch .
+
+docker push ghcr.io/dune-daq/microservices:user-my-branch
 ```
+and 
+
+```bash
+docker build -f dockerfiles/microservices-dependencies.dockerfile -t ghcr.io/dune-daq/microservices_dependencies:user-my-branch /dockerfiles
+
+docker push ghcr.io/dune-daq/microservices_dependencies:user-my-branch
+```
+
+This will copy your current microservices directory.
