-## GTK CI infrastructure
-
-GTK uses different CI images depending on platform and jobs.
-
-The CI images are Docker containers, generated either using `docker` or
-`podman`, and pushed to the GitLab [container registry][registry].
-
-Each Docker image has a tag composed of two parts:
-
- - `${image}`: the base image for a given platform, like "fedora" or
-   "debian-stable"
- - `${number}`: an incremental version number, or `latest`
-
-See the [container registry][registry] for the available images for each
-branch, as well as their available versions.
-
-Note that using `latest` as version number will overwrite the most
-recently uploaded image in the registry.
-
-### Checklist for Updating a CI image
-
- - [ ] Update the `${image}.Dockerfile` file with the dependencies
- - [ ] Run `./run-docker.sh build --base ${image} --version ${number}`
- - [ ] Run `./run-docker.sh push --base ${image} --version ${number}`
-   once the Docker image is built; you may need to log in by using
-   `docker login` or `podman login`
- - [ ] Update the `image` keys in the `.gitlab-ci.yml` file with the new
-   image tag
- - [ ] Open a merge request with your changes and let it run
-
-### Checklist for Adding a new CI image
-
- - [ ] Write a new `${image}.Dockerfile` with the instructions to set up
-   a build environment
- - [ ] Add the `pip3 install meson` incantation
- - [ ] Run `./run-docker.sh build --base ${image} --version ${number}`
- - [ ] Run `./run-docker.sh push --base ${image} --version ${number}`
- - [ ] Add the new job to `.gitlab-ci.yml` referencing the image
- - [ ] Open a merge request with your changes and let it run
-
-### Checklist for Adding a new dependency to a CI image
-
-Our images are layered, and the base (called fedora-base) contains
-all the rpm payload. Therefore, adding a new dependency is a 2-step
-process:
-
- 1. [ ] Build and upload fedora-base:$version+1
- 1. [ ] Build and upload fedora:$version+1 based on fedora-base:version+1
