 # Manage a hub's user environment
 
-## Update the default user environment
-
-The default user environment is specified in its own GitHub repository, located
-at <https://github.com/2i2c-org/2i2c-hubs-image>.
-
-The image is built and pushed using [jupyterhub/repo2docker-action](https://github.com/jupyterhub/repo2docker-action) to the [2i2c-hubs-image repository](https://quay.io/repository/2i2c/2i2c-hubs-image) on quay.io.
-
-To update this environment:
-
-1. Make the changes you need to make to the environment, by editing the files in
-   the [2i2c-hubs-image repository](https://github.com/2i2c-org/2i2c-hubs-image)
-   and open a pull request. This will also provide you the ability to test your
-   changes on Binder to make sure everything works as expected.
-2. Once the PR is merged or a commit to the `main` branch happens, the new image will be pushed
-   to the registry.
-3. Get the latest tag from the [tags section](https://quay.io/repository/2i2c/2i2c-hubs-image?tab=tags) in quay.io
-4. Update `jupyterhub.singleuser.image.tag` in `helm-charts/basehub/values.yaml` with this tag.
